PIN
Description
1- VCC
IC positive supply pin.
The chip behaves like a 4 volt zener diode referenced to GND
2- VS
Voltage sensing pin.
This is the inverting input of the voltage error amplifier. The positive input of the amplifier is connected
to an internal trimmed 1.20V voltage reference. An external voltage divider connected to this point sets
the output voltage. This pin is also used for voltage loop compensation when required.
3- VCOMP
Voltage loop compensation pin.
This is the output of the voltage error amplifier. The voltage loop compensation network, when required,
is connected between this point and VS pin. Please note that this pin is not a zero-impedance node (1K
Ω
nominal).
4- OPTO
Optocoupler driver pin.
This pin drives and external optocoupler connected to GND. A current-mode drive is used for maximum
noise rejection.
5- ICOMP
Current loop compensation pin. (similar to VCOMP)
This is the output of the current error amplifier. The current loop compensation network, when required,
is connected between this point and the IS pin. Please note that this is not a zero-impedance point (1K
Ω
nominal).
6- IS
Current sensing pin.
This pin is the inverting input of the current sense amplifier. The positive input of the amplifier is
connected to an internal trimmed reference. The sensing threshold is 50mV PTAT (IPS20) or 100mV
constant (IPS21). This pin should be connected through a resistor to the external current sensing resistor.
7- OUT (-)
Negative output pin.
This pin is the negative side of the 1.20V trimmed voltage reference. It should be connected to the
negative output of the SMPS.
8- GND
Ground pin.
This is the most negative IC pin. The first output decoupling capacitor should return to it. Do not confuse
this pin with the IS pin and the OUT(-) pin which are described above.
