threshold voltage (V IT )or the MR pin is set to a logic low).RESET remains RESET 1low (asserted)for the reset period after both SENSE is above V IT and MR is set to a logic high.A pullupresistor from 10k Ωto 1M Ωshould be used on this pin,and allows the reset pin to attain voltages higher than V DD .GND 2GroundMR 3Manual reset.Driving this pin low asserts RESET.MR is internally tied to V DD by a

).Connecting this pin to a ground referenced capacitor ≥100pF gives a user-programmable delay time.Voltage sense.This pin is connected to the voltage to be monitored.If the voltage at this terminal

8.=(1+)0.405R 1R 2TPS3808-Q1SBVS085H –JANUARY 2007–REVISED JUNE 2012DEVICE OPERATIONThe TPS3808microprocessor supervisory product family is designed to assert a RESET signal when either the SENSE pin voltage drops below V IT or the manual reset (MR)is driven low.The RESET output remains asserted for a user-adjustable time after both the manual reset (MR)and SENSE voltages return above the respective thresholds.A broad range of voltage threshold and reset delay time adjustments are available,allowing these devices to be used in a wide array of applications.Reset threshold voltages can be factory-set from 0.82V to 3.3V or from 4.4V to 5.0V,while the TPS3808G01can be set to any voltage above 0.405V using an external resistor divider.Two preset delay times are also user-selectable:connecting the C T pin to V DD results in a 300-ms reset delay,while leaving the C T pin open yields a 20-ms reset delay.In addition,connecting a capacitor between C T and GND allows the designer to select any reset delay period from 1.25ms to 10s.SENSE InputThe SENSE input provides a terminal at which any system voltage can be monitored.If the voltage on this pin drops below V IT ,RESET is asserted.The comparator has a built-in hysteresis to ensure smooth RESET assertions and deassertions.It is good analog design practice to put a 1-nF to 10-nF bypass capacitor on the SENSE input to reduce sensitivity to transients and layout parasitics.The TPS3808G01can be used to monitor any voltage rail down to 0.405V using the circuit shown in Figure 9.Figure ing the TPS3808G01to Monitor a User-Defined Threshold VoltageManual Reset (MR)InputThe manual reset (MR)input allows a processor or other logic circuits to initiate a reset.A logic low (0.3V DD )on MR causes RESET to assert.After MR returns to a logic high and SENSE is above its reset threshold,RESET is deasserted after the user-defined reset delay expires.Note that MR is internally tied to V DD using a 90-k Ωresistor,so this pin can be left unconnected if MR is not used.Refer to Figure 10for how MR can be used to monitor multiple system voltages.Note that if the logic signal driving MR does not go fully to V DD ,there will be some additional current draw into V DD as a result of the internal pullup resistor on MR.To minimize current draw,a logic-level FET can be used as shown in Figure 11.Figure ing

2012Figure ing an External MOSFET to Minimize I DD When MR Signal Does Not Go to V DDSelecting the Reset Delay TimeThe TPS3808has three options for setting the RESET delay time as shown in Figure 12.Figure 12a shows the configuration for a fixed 300-ms typical delay time by tying C T to V DD ;a resistor from 40k Ωto 200k Ωmust be used.Supply current is not affected by the choice of resistor.Figure 12b shows a fixed 20-ms delay time by leaving the C T pin open.Figure 12c shows a ground referenced capacitor connected to C T for a user-defined program time between 1.25ms and 10s.The capacitor C T should be ≥100pF nominal value in order for the TPS3808to recognize that the capacitor is present.The capacitor value for a given delay time can be calculated using the following equation:(1)The reset delay time is determined by the time it takes an on-chip precision 220-nA current source to charge the external capacitor to 1.23V.When a RESET is asserted,the capacitor is discharged.When the RESET conditions are cleared,the internal current source is enabled and begins to charge the external capacitor.When the voltage on this capacitor reaches 1.23V,RESET is deasserted.Note that a low-leakage type capacitor such as a ceramic should be used and that stray capacitance around this pin may cause errors in the reset delay time.Immunity to SENSE Pin Voltage TransientsThe TPS3808is relatively immune to short negative transients on the SENSE pin.Sensitivity to transients is dependent on threshold overdrive,as shown in the Maximum Transient Duration at Sense vs Sense Threshold Overdrive Voltage graph (Figure 5)in the Typical Characteristics section.Figure 12.Configuration Used to Set the RESET Delay TimeTPS3808-Q1SBVS085H–JANUARY2007–REVISED

LTC3805-5 DESCRIPTIONDemonstration circuit 1576 is high efficiency non-isolated SEPIC (Single Ended Primary Inductor Con-verter) converter featuring the LTC3805-5 switching controller. The DC1576 converts 5V to 30V input to 12V output and provides over 3A of output current. The converter operates at 300kHz with efficiency over 90%. With proper amount of airflow, the DC1576 con-verter can generate over 3A of output current. The DC1576 can be easily modified to generate output voltages in the range from 0.8V to 48V.Also, the DC1576 can be modified for other input volt-ages like 5V-36V, 9V-36V, 36V-72V, and so on. The wider input voltage range will decrease the converter efficiency. Therefore, narrow input voltage range will be more desirable.The LTC3805-5 can be synchronized to an external clock of up to 400kHz. Please refer to LTC3805-5 data sheet for design details and applications information. Design files for this circuit board are available.

Refer to Figure 1 for proper measurement equipment setup and follow the procedure below:NOTE:When measuring the input or output volt-age ripple, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the input or output voltage ripple by touching the probe tip directly across the Vin or Vout and GND terminals. See Figure 2. for proper scope probe technique.1.With power off, connect the input power supply toVin and GND. Make sure that the input power sup-ply has sufficient current rating at minimum input voltage for the required output load.2.Turn on the power at the input.NOTE:Make sure that the input voltage does not exceed 30V.3.Check for the proper output voltage.Vout = 12V, +/-3%.If there is no output, temporarily disconnect the load to make sure that the load is not set too high.4.Once the proper output voltage is established, ad-just the load within the operating range and ob-DEMO CIRCUIT 1576AQUICK START GUIDELTC3805-5Low Noise SEPIC DC/DC Converterserve the output voltage regulation, ripple voltage, efficiency and other parameters.5. The DC1576 is equipped with an output capacitor C OUT4 (150uF) that approximates typical system rail capacitance. If system board already has capaci-tance ofsimilar value C OUT4 can be removed. Theinput capacitor Cin1 is optional and is used to help with filtering when board is connected to lab sup-ply with long leads. The capacitor Cin1 can be re-moved if the input power source is close and has low source impedance.Figure 1.Proper Measurement Equipment SetupFigure 2. Measuring Input or Output RippleCHANGING THE OUTPUT VOLTAGETo set the output voltage lower than 12V, change the bottom voltage divider resistor connected to FB pinof U1 (see the schematic on page 5). For example, to get 9V output, change R3 resistor value to 11k.However, keep in mind that changing the trans-former as well may increase the efficiency.The optional Q1 circuit is used to get the circuit run-ning. Once the circuit is running, the 12V output is used to bias U1 via D2. The startup circuit Q1 is turned off by pulling the emitter of Q1 above 7V. Please contact LTC factory for details.Figure 3. High efficiency of DC1576 allows the board to be used in thermally critical applications with outputs over 3A.OUTPUT LOAD STEP RESPONSEThe load step response of DC1576 is very fast even though relatively small amount of output capacitance is present (100uF ceramic and 150uF electrolytic). The load step transients are shown in Figure 4. To improve load step response further or to reduce the output ripple, more output capacitance can be added. Low ESR output caps will have greatest effect on reducing the ripple and load step transients.Figure 4. Fast transient response of DC1576 is achieved with a small amount of output capacitance.SOFT START FUNCTIONThe DC1576 features soft-start circuit that controls the inrush current and output voltage ramp at startup. The capacitor C SS controls the startup pe-riod. The startup waveforms are shown in figure 5.Figure 5. The DC1576 ramps the output slowly at startup without generating an input current surge.。

·WG-3000 ·WG-5000 ·WG-8000交流自动稳压器说明书使用前请认真阅读本说明书感谢您选用了‘JUTA’牌交流自动稳压器，愿我们的产品及服务能为您带来更多方便和实惠功能：在市电输入变化时自动调整稳压输出，确保家用电器在恶劣的电网条件下也能正常运行；同时具备了全方位保护及实用的稳压、市电直通功能，使用方便，更安全更可靠，大大延长了家用电器的使用寿命。

⊙稳压精确：在电网电压变化不稳时，能输出稳定的安全电压，使用电器不受影响。

⊙输入欠压、过压保护：由电网及其他因素引起的电压输入过高或过低时，为保证用电器和人身财产安全，稳压器会自动切断输出，待电网电压恢复稳定后可自动（延时）开启。

⊙缺相保护：在三相供电情况下，由于一相断掉或者零线断掉，会导致单相供电电压异常升高，甚至高过380V，危及到用电器及人身财产安全，此时稳压器会自动关闭输出进入保护状态。

⊙误断电保护：在遇到电网老化、输电线过细距离过长时，有感性负载（如冰箱、空调等带有压缩机的）或大型用电器启动，瞬间会导致电网电压降低，此时稳压器能保证负载的正常供电而不至于误断电。

⊙市电稳压切换：机身侧面设有稳压接入和市电直通转换开关，使用时若觉得电网电压很稳定，不想用稳压功能时，把此开关拨至“OFF”市电状态即可。

通常情况下都要将此开关拨至“ON”稳压状态，此时自动稳压功能才能启动。

⊙延时供电功能：为避免短时间停电又来电情况的发生，设有了2-3分钟自动延时供电功能（如电冰箱或空调器在停止工作后，再次启动需3分钟延时）；若不需要此延时，可按下“延时开关”按钮启动短延时，本机可在5秒内开启供电。

安装连接：(如图所示)将启动开关拨至“OFF”关状态，拉下电网闸刀开关或空气开关断开市电，取下稳压器端子板两颗固定螺丝拔出端子板，按对应端位指示正确连接1.把家庭供电总线（墙壁插座及所有用电器用线）插入到对应输出的“火线”、“零线”端口内，拧紧固定螺丝。
