HA17431 Series
Shunt Regulator
Description
The HA17431 series is a family of voltage referenced shunt regulators. The main application of these products is in voltage regulators that provide a variable output voltage. The HA17431 series products are provided in a wide range of packages; TO-92 and TO-92MOD insertion mounting packages and MPAK-5, UPAK, and FP-8D surface mounting packages are available. The on-chip high-precision reference voltage source can provide 1% accuracy in the V versions, which have a VKA max of 16 volts. The HA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode power supplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be easily constructed on the supply side.

Application Examples
As shown in the figure on the right, this IC operates as an inverting amplifier, with the REF pin as input pin. The open-loop voltage gain is given by the reciprocal of "reference voltage deviation by cathode voltage 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 A Typ (V version: Iref = 2 A Typ). The output impedance of the output pin K (cathode) is defined as dynamic impedance Z KA , and ZKA is low (0.2 ) over a wide cathode current range. A (anode) is used at the minimum potential, such as ground.

This is an AC amplifier with voltage gain G = -R1 / (R2//R3). 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. R2 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 VCC, this can be omitted. To change the frequency characteristic, Cf should be connected as indicated by the dotted line.

Switching power supply error amplification circuit
R4 + - R1 (Note) Secondary side GND Cf R2 - LED R3 + V
This 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 x (R1 + R2) R2
In this circuit, the gain with respect to the Vout error is as follows: G= R2 x HA17431 open x photocoupler total gain (R1 + R2) loop gain
V Note: LED : Light emitting diode in photocoupler R3 : Bypass resistor to feed IK(>Imin) when LED current vanishes R4 : LED protection resistance
As stated earlier, the HA17431 open-loop gain is 50 to 60 dB.

Description This is a 3-pin regulator with a discrete configuration, in which the output voltage Vout = 2.5 V x (R2 + R3) R3

Discharge type constant current circuit
VCC R Q
This circuit supplies a constant current of IL 2.5 V RS [A] into the load. Caution is required
since 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 IL setting therefore must be on the order of several mA or more.

In 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 IL, so that IL can be kept small (1 mA or less is possible). The constant current value is the same as for circuit 7 above: IL 2.5 V RS [A]

Figure 2 Typical Shunt Regulator/Error Amplifier Determination of External Constants for the Shunt Regulator DC characteristic determination: In figure 2, R1 and R2 are protection resistor for the light emitting diode in the photocoupler, and R2 is a bypass resistor to feed IK minimum, and these are determined as shown below. The photocoupler specification should be obtained separately from the manufacturer. Using the parameters in figure 2, the following formulas are obtained:
R1 = V0 - VF - VK V , R2 = F IF + IB IB
VK is the HA17431 operating voltage, and is set at around 3 V, taking into account a margin for fluctuation. R 2 is the current shunt resistance for the light emitting diode, in which a bias current I B of around 1/5 IF flows. Next, the output voltage can be determined by R3 and R4, and the following formula is obtained:
V0 = R3 + R4 x Vref, Vref = 2.5 V Typ R4
The absolute values of R3 and R4 are determined by the HA17431 reference input current Iref and the AC characteristics described in the next section. The Iref value is around 3.8 A Typ. (V version: 2 A Typ)

Practical Example Consider the example of a photocoupler, with an internal light emitting diode VF = 1.05 V and I F = 2.5 mA, power supply output voltage V2 = 5 V, and bias resistance R2 current of approximately 1/5 IF at 0.5 mA. If the shunt regulator VK = 3 V, the following values are found.
R1 = R2 = 5V - 1.05V - 3V = 316() (330 from E24 series) 2.5mA + 0.5mA 1.05V = 2.1(k) (2.2k from E24 series) 0.5mA
Next, assume that R3 = R4 = 10 k. This gives a 5 V output. If R5 = 3.3 k and C1 = 0.022 F, the following values are found.
G2 = 3.3 k / 10 k = 0.33 times (-10 dB) f 1 = 1 / (2 x x 0.022 F x 316 x 10 k) = 2.3 (Hz) f 2 = 1 / (2 x x 0.022 F x 3.3 k) = 2.2 (kHz)
