The open-loop voltage gain is given by the reciprocal of “reference voltage deviation by cathodevoltage change ” in the electrical specifications, and is approximately 50 to 60 dB. The REF pin has a high input impedance, with an input current Iref of 3.8 µA Typ (V version: Iref = 2 µA Typ). The outputimpedance of the output pin K (cathode) is defined as dynamic impedance Z KA , and Z KA is low (0.2 Ω) over a wide cathode current range. A (anode) is used at the minimum potential, such as ground.Figure 1 Operation DiagramApplication HintsNo. Application Example Description1Reference voltage generation circuitVoutGND VinGNDThis is the simplest reference voltage circuit. The valueof the resistance R is set so that cathode current I K ≥ 1 mA.Output is fixed at Vout ≅ 2.5 V.The external capacitor C L (C L ≥ 3.3 µF) is used to prevent oscillation in normal applications.2 Variable output shunt regulator circuitThis is circuit 1 above with variable output provided.Vout ≅ 2.5 V ×Here,(R 1 + R 2)R 2Since the reference input current Iref = 3.8 µA Typ (V version: Iref = 2 µA Typ) flows through R 1, resistance values are chosen to allow the resultant voltage drop to be ignored.3Single power supply invertingcomparator circuitThis is an inverting type comparator with an input threshold voltage of approximately 2.5 V. Rin is the REF pin protection resistance, with a value of several k Ω to several tens of k Ω.R L is the load resistance, selected so that the cathode current I K • 1 mA when Vout is low.Condition C1C2Vin Less then 2.5 V 2.5 V or moreVout V CC (V OH )Approx. 2 V (V OL )ICOFF ON4 AC amplifier circuitGain G =(DC gain)R 1R 2 // R 3Cutoff frequency fc =12π Cf (R 1 // R 2 // R 3)This is an AC amplifier with voltage gain G = –R 1 / (R 2//R 3). The input is cut by capacitance Cin, so that the REF pin is driven by the AC input signal, centered on 2.5 V DC .R 2 also functions as a resistance that determines the DC cathode potential when there is no input, but if the input level is low and there is no risk of Vout clipping to V CC , this can be omitted.To change the frequency characteristic, Cf should be connected as indicated by the dotted line.5Switching power supply erroramplification circuit12Note:LED R3R4: Light emitting diode in photocoupler : Bypass resistor to feed IK(>Imin) when LED current vanishes : LED protection resistanceThis circuit performs control on the secondary side of a transformer, and is often used with a switching power supply that employs a photocoupler for offlining.The output voltage (between V+ and V –) is given by the following formula:Vout ≅ 2.5 V ×(R 1 + R 2)R 2In this circuit, the gain with respect to the Vout error is as follows:G =×R 2(R 1 + R 2)HA17431 open loop gain ×photocoupler total gainAs stated earlier, the HA17431 open-loop gain is 50 to60 dB.6Constant voltage regulator circuitV CCVoutGNDGNDThis is a 3-pin regulator with a discrete configuration, inwhich the output voltageVout = 2.5 V ×(R 2 + R 3)R 3R 1 is a bias resistance for supplying the HA17431 cathode current and the output transistor Q base current.7Discharge type constant current circuitV SI LThis circuit supplies a constant current ofI L ≅[A] into the load. Caution is required2.5 V R Ssince the HA17431 cathode current is also superimposed on IL .The requirement in this circuit is that the cathode current must be greater than Imin = 1 mA. The I Lsetting therefore must be on the order of several mA or more.8Induction type constant current circuitV I L SIn this circuit, the load is connected on the collector side of transistor Q in circuit 7 above. In this case, the load floats from GND, but the HA17431 cathode current is not superimposed on I L , so that I L can be kept small (1 mA or less is possible). The constant current value is the same as for circuit 7 above:I L ≅[A]2.5 V R SDesign Guide for AC-DC SMPS (Switching Mode Power Supply)Use of Shunt Regulator in Transformer Secondary Side ControlThis example is applicable to both forward transformers and flyback transformers. A shunt regulator is used on the secondary side as an error amplifier, and feedback to the primary side is provided via a photocoupler.Figure 2 Typical Shunt Regulator/Error AmplifierDetermination of External Constants for the Shunt RegulatorDC characteristic determination: In figure 2, R1 and R2are protection resistor for the light emitting diodein the photocoupler, and R2 is a bypass resistor to feed IKminimum, and these are determined as shownbelow. The photocoupler specification should be obtained separately from the manufacturer. Using the parameters in figure 2, the following formulas are obtained:R1 =V0– V F– V KI F + I B, R2 =V FI BVKis the HA17431 operating voltage, and is set at around 3 V, taking into account a margin for fluctuation.R2 is the current shunt resistance for the light emitting diode, in which a bias current IBof around 1/5 IFflows.Next, the output voltage can be determined by R3 and R4, and the following formula is obtained:V0 =R3 + R4R4× Vref, Vref = 2.5 V TypThe absolute values of R3 and R4are determined by the HA17431 reference input current Iref and the ACcharacteristics described in the next section. The Iref value is around 3.8 µA Typ. (V version: 2 µA Typ)AC characteristic determination: This refers to the determination of the gain frequency characteristic of the shunt regulator as an error amplifier. Taking the configuration in figure 2, the error amplifier characteristic is as shown in figure 3.Figure 3 HA17431 Error Amplification CharacteristicIn Figure 3, the following formulas are obtained: GainG 1 = G 0 ≈ 50 dB to 60 dB (determined by shunt regulator)G 2 =R 5R 3Corner frequenciesf 1 = 1/(2π C 1 G 0 R 3) f 2 = 1/(2π C 1 R 5)G 0 is the shunt regulator open-loop gain; this is given by the reciprocal of the reference voltage fluctuation ∆Vref/∆V KA , and is approximately 50 dB.Practical ExampleConsider the example of a photocoupler, with an internal light emitting diode V F = 1.05 V and I F = 2.5 mA, power supply output voltage V 2 = 5 V, and bias resistance R 2 current of approximately 1/5 I F at 0.5 mA. If the shunt regulator V K = 3 V, the following values are found.R 1 =5V – 1.05V – 3V2.5mA + 0.5mA= 316(Ω) (330Ω from E24 series)R 2 =1.05V0.5mA= 2.1(k Ω) (2.2k Ω from E24 series)Next, assume that R 3 = R 4 = 10 k Ω. This gives a 5 V output. If R 5 = 3.3 k Ω and C 1 = 0.022 µF, the following values are found.G 2 = 3.3 k Ω / 10 k Ω = 0.33 times (–10 dB) f 1 = 1 / (2 × π × 0.022 µF × 316 × 10 k Ω) = 2.3 (Hz) f 2 = 1 / (2 × π × 0.022 µF × 3.3 k Ω) = 2.2 (kHz)Package DimensionsDisclaimer1.
