PIN DESCRIPTION

A resistor divider connected from this pin to Vref programs the current limit thresh-

old. The outputs of the internal current sense differential amplifiers are summed

together to represent the output current. This voltage is then compared to this thresh-

old.

VREF A 1.6V buffered reference is brought out.

ENBUS

This pin is used to program the under voltage lockout of the bus supply. A resistor

divider from the bus voltage to this pin programs the under voltage lockout. When

the voltage of this pin is greater than 1.6V, the bus voltage is assumed in operation.

The pin has a 10% hysterisis.

PGND1, This is the ground connection for the power stage of the controller.

PGND2

AGND Controller analog ground pin.

IOUT

Input of OCP amplifier. Place a 10nF to 100nF capacitor from this pin to GND to

filter any noise.

PGSEN Output over voltage and Pgood sensing pin. A resistor divider plus a small capacitor

should be connected to the this pin to set the OVP and Pgood.
