Functional Pin Description
PHASE2 (Pin 23)
Connect this pin to the PWM2 converter’s MOSFET
source.This pin is used to monitor the voltage drop
across the MOSFET for over-current protection.
UGATE2 (Pin 24)
Connect this pin to the MOSFET gate of the PWM2
converter. This pin provides the gate drive for the
MOSFET.
