(1)This device can regulate V OUT down to0A,however the ripple may increase due to pulse-skipping at light loads.See Light-Load
Behavior for more information.See No-Load Operation when operating at0A.
(2)The maximum current is dependant on V IN and V OUT,see Figure33.
(3)The sum of V IN+|V OUT|must not exceed50V.
(4)The stated limit of the set-point voltage tolerance includes the tolerance of both the internal voltage reference and the internal
adjustment resistor.The overall output voltage tolerance will be affected by the tolerance of the external R SET resistor.
(5)This product is not designed to endure a sustained(>5sec)over-current condition.
(6)If this pin is left open circuit,the device operates when input power is applied.An external level-shifter is required to interface with this
pin.See Output On/Off Inhibit(INH)for further guidance.
(7)The synchronization frequency is dependant on V IN and V OUT as shown in Switching Frequency.R RT must be either0Ωor93.1kΩ.
(8)A minimum of4.7μF of ceramic external capacitance is required across the input(VIN and PGND connected)for proper operation.
Locate the capacitor close to the device.See Table1for more details.
(9)The amount of required capacitance must include at least2x47μF ceramic capacitor(or4x22μF).Locate the capacitance close to
the device.Adding additional capacitance close to the load improves the response of the regulator to load transients.See Table1for more details.See Inrush Current section when adding additional output capacitance.

CAPACITOR RECOMMENDATIONS FOR THE LMZ34002POWER SUPPLY
Capacitor Technologies
Electrolytic,Polymer-Electrolytic Capacitors
When using electrolytic capacitors,high-quality,computer-grade electrolytic capacitors are recommended.
Polymer-electrolytic type capacitors are recommended for applications where the ambient operating temperature
is less than 0°C.The Sanyo OS-CON capacitor series is suggested due to the lower ESR,higher rated surge,
power dissipation,ripple current capability,and small package size.Aluminum electrolytic capacitors provide
adequate decoupling over the frequency range of 2kHz to 150kHz,and are suitable when ambient temperatures
are above 0°C.
Ceramic Capacitors
The performance of aluminum electrolytic capacitors is less effective than ceramic capacitors above 150kHz.
Multilayer ceramic capacitors have a low ESR and a resonant frequency higher than the bandwidth of the
regulator.They can be used to reduce the reflected ripple current at the input as well as improve the transient
response of the output.
Tantalum,Polymer-Tantalum Capacitors
Polymer-tantalum type capacitors are recommended for applications where the ambient operating temperature is
less than 0°C.The Sanyo POSCAP series and Kemet T530capacitor series are recommended rather than many
other tantalum types due to their lower ESR,higher rated surge,power dissipation,ripple current capability,and
small package size.Tantalum capacitors that have no stated ESR or surge current rating are not recommended
for power applications.
Input Capacitor
The LMZ34002requires a minimum input capacitance of 4.7μF of ceramic type.The voltage rating of input
capacitors must be greater than the maximum input voltage.The ripple current rating of the capacitor must be at
least 450mArms.Table 1includes a preferred list of capacitors by vendor.
Output Capacitor
The required output capacitance of the LMZ34002can be comprised of either all ceramic capacitors,or a
combination of ceramic and bulk capacitors.The required output capacitance must include at least 2×47μF of
ceramic type (or 4×22μF).The voltage rating of output capacitors must be greater than the output voltage.
When adding additional non-ceramic bulk capacitors,low-ESR devices like the ones recommended in Table 1
are required.Additional capacitance above the required minimum is determined by actual transient deviation
requirements.Table 1includes a preferred list of capacitors by vendor.

APPLICATION INFORMATION
Adjusting the Output Voltage
The LMZ34002is designed to provide output voltages from –3V to –17V.The output voltage is determined by
the value of R SET ,which must be connected between the VADJ pin (Pin 36)and GND.Table 2gives the
standard external R SET resistor for a number of common bus voltages.

Input Voltage
The LMZ34002operates over the input voltage range of 4.5V to 40V.The maximum input voltage is 40V,
however,the sum of V IN +|V OUT |must not exceed 50V.
See the Undervoltage Lockout (UVLO)Threshold section of this datasheet for more information.
Undervoltage Lockout (UVLO)Threshold
At turn-on,the V ON UVLO threshold determines the input voltage level where the device begins power
conversion.R UVLO1and R UVLO2set the turn-on threshold as shown in Figure 36.The UVLO threshold is not
present during the power-down sequence.Applications requiring a turn-off threshold must monitor the input
voltage with external circuitry and shut-down using the INH control (see Output On/Off Inhibit (INH)).
The V ON UVLO threshold must be set to at least 4.5V to insure proper start-up and reduce current surges on the
host input supply as the voltage rises.If possible,it is recommended to set the UVLO threshold to
appproximantely 80to 85%of the minimum expected input voltage.
Use Equation 2and Equation 3to calculate the values of R UVLO1and R UVLO2.V ON is the voltage threshold during
power-up when the input voltage is rising.Table 4lists standard resistor values for R UVLO1and R UVLO2for
adjusting the V ON UVLO threshold for several input voltages.

Power-Up Characteristics
When configured as shown in the application schematics,the LMZ34002produces a regulated output voltage following the application of a valid input voltage.During the power-up,internal soft-start circuitry slows the rate that the output voltage rises,thereby limiting the amount of in-rush current that can be drawn from the input source.The soft-start circuitry introduces a short time delay from the point that a valid input voltage is recognized.Figure37shows the start-up waveforms for a LMZ34002,operating from a12V input and the output voltage adjusted to–5V.The waveform were measured with a1.5-A constant current load.
Figure37.Start-Up Sequence
Light-Load Behavior
The LMZ34002is a non-synchronous converter.One of the characteristics of non-synchronous operation is that as the output load current decreases,a point is reached where the energy delivered by a single switching pulse is more than the load can absorb.This energy causes the output voltage to rise slightly.This rise in output voltage is sensed by the feedback loop and the device responds by skipping one or more switching cycles until the output voltages falls back to the set point.At very light loads or no load,many switching cycles are skipped. The observed effect during this pulse skipping mode of operation is an increase in the peak to peak ripple voltage,and a decrease in the ripple frequency.The amount of load current when pulse skipping begins is a function of the input voltage,the output voltage,and the switching frequency.
No-Load Operation
When operating at no load or very light load and the input voltage is removed,the output voltage discharges very slowly.If the input voltage is re-applied before the output voltage discharges,the slow-start circuit does not activate and the amount of inrush current is extremely large and may cause an over-current condition.To avoid this condition the output voltage must be allowed to discharge before re-applying the input voltage.Applying a 50-mA to100-mA minimum load helps discharge the output voltage.Additionally,monitoring the input voltage with a supervisor and shuting-down using the INH control(see Output On/Off Inhibit(INH))activates the internal slow-start circuit.

Switching Frequency
The recommended switching frequency of the LMZ34002is 800kHz.To operate at the recommended switching
frequency,connect the RT pin (Pin 30)to A_VOUT (at pin 32).
It is recommended to adjust the switching frequency in applications with both,higher input voltage (>18V)and
lower output voltage (<–8V).For these applications,improved operating performance can be obtained by
decreasing the operating frequency to 500kHz by adding a resistor,R RT of 93.1k Ωbetween the RT pin and
A_VOUT as shown in Figure 38.Figure 39shows the recommended switching frequency over input voltage and
output voltage.

Synchronization (CLK)
An internal phase locked loop (PLL)allows synchronization from 700kHz to 900kHz for 800kHz applications,or
400kHz to 600kHz for 500kHz applications.See Figure 39to determine switching frequency based on input
voltage and output voltage.To implement the synchronization feature,connect a square wave clock signal to the
RT/CLK pin with a duty cycle between 25%to 75%.The clock signal amplitude must transition lower than 0.5V
and higher than 2.2V.The start of the switching cycle is synchronized to the falling edge of RT/CLK pin.In
applications requiring CLK mode,configure the device as shown in Figure 40(800kHz)and Figure 41(500kHz).
Before the external clock is present,the device works in RT mode where the switching frequency is set by the
R RT resistor.When the external clock is present,the CLK mode overrides the RT mode.The first time the CLK
pin is pulled above the RT/CLK high threshold (2.2V),the device switches from RT mode to CLK mode and the
CLK pin becomes high impedance as the PLL starts to lock onto the frequency of the external clock.It is not
recommended to switch from CLK mode back to RT mode because the internal switching frequency drops to 100
kHz first before returning to the switching frequency set by the RT resistor.

Output On/Off Inhibit (INH)
The INH pin provides electrical on/off control of the device.Once the INH pin voltage exceeds the threshold
voltage,the device starts operation.If the INH pin voltage is pulled below the threshold voltage,the regulator
stops switching and enters low quiescent current state.
The INH pin has an internal pull-up current source,allowing the user to float the INH pin for enabling the device.
If an application requires controlling the INH pin,an external level-shifter is required to interface with the pin
because in a positive-to-negative buck-boost supply,the INH pin is referenced to VOUT,not GND.Adding a
level-shifter (U1)as shown in Figure 42,allows the INH control to be refernced to GND.A recommended level-
shifter part #is DCX144EH-7from Diodes Inc.
Pulling the input of U1to GND applies a low voltage to the inhibit control pin and disables the output of the
supply,shown in Figure 43.Releasing the input of U1enables the device,which executes a soft-start power-up
sequence,as shown in Figure 44.The device produces a regulated output voltage within 10ms.The waveforms
were measured with a 1.5-A constant current load.

Slow-Start Circuit (SS)
Connecting the STSEL pin (Pin 29)to A_VOUT while leaving SS pin (Pin 28)open,enables the internal SS
capacitor with a slow-start interval of approximately 10ms.Adding additional capacitance between the SS pin
and A_VOUT increases the slow-start time.Figure 45shows an additional SS capacitor connected to the SS pin
and the STSEL pin connected to A_VOUT.See Table 6below for SS capacitor values and timing interval.

Inrush Current
During turn-on,as the LMZ34002performs a slow-start sequence,an inrush current is induced as the output
capacitors charge up.The inrush current is in addition to the DC input current.The amount of inrush current
depends on the input voltage,output voltage and amount of output capacitance.Table 7shows the typical inrush
current for the input voltage,output voltage and the amount of output capacitance.Increasing the slow-start
capacitor reduces the inrush current by slowing down the ramp of the output voltage.See Slow-Start Circuit (SS).

Pierce? Co-Immunoprecipitation (Co-IP) Kit（26149） 中文说明书 介绍： Thermo 公司的Pierce?免疫共沉淀试剂盒，可通过将铆钉抗体固定在琼脂 糖支撑物上，从裂解液中或其他复杂混合物中，分离出天然蛋白复合物。Co-IP 是一种研究蛋白与蛋白相互作用通用的方法，该方法使用一种诱饵蛋白与抗原 进行免疫沉淀反应，然后可通过免疫共沉淀任何与诱饵蛋白具有相互作用的猎 物蛋白。传统的Co-IP方法使用蛋白A或G共同洗脱抗体的重链和轻链，这很 可能导致将相关的蛋白一起洗脱下来，掩盖一些重要的结果。Pierce?免疫共沉 淀试剂盒通过将共价结合抗体固定在一个胺类活性反应树脂上解决了这一问题。该试剂盒包含足够的用于蛋白结合和恢复的缓冲液，完成对照试验的高校离心 柱和收集管，这些产品进一步缩短了操作实验的时间。 重要产品信息： 略 Co-IP实验步骤： A.抗体固定 注意：以下试验步骤是针对用无胺和其他载体蛋白稀释的10-75μg亲和纯 化抗体（参考重要产品信息一节）。根据实际使用比例参考这一协议步骤。参 考重要产品信息节表1中的建议抗体用量和树脂体积用量。 1.室温平衡胺连接耦合树脂（AminoLink?Plus Coupling Resin）和试剂； 2.为每个Co-IP反应准备2ml 1×Coupling Buffer（超纯水稀释20×Coupling Buffer）；
