Function

29

OUT1

Output voltage sense for the switching section 1.This pin must be directly

connected to the output voltage of the switching section.

30

COMP1 DC voltage error compensation pin for the switching section 1.

31

VCC

Device Supply Voltage pin. It supplies all the internal analog circuitry except

the gate drivers (see LDO5). Connect this pin to LDO5.

32

VREF

Internal 1.237 V high accuracy voltage reference. It can deliver 50 uA.

Bypass to SGND with a 100 nF capacitor to reduce noise.
