NAME

FUNCTION

21

UGATE1

Output of The High-Side MOSFET Driver for PWM1. Connect this pin to Gate of the high-side MOSFET.

22

BOOT1

Supply Input for The UGATE1 Gate Driver and an internal level-shift circuit. Connect to an external capacitor

to create a boosted voltage suitable to drive a logic-level N-channel MOSFET.

23

POK

Power-Good Output Pin of Both PWMs.(Logic AND) POK is an open-drain output used to indicate the status

of the PWMx output voltage. Connect the POK in to +5V through a pull-high resistor.

24

VOUT1

PWM1 Output Voltage-Sense Input. The VOUT1 pin makes a direct measurement of the PWM1 output

voltage. VOUT1 is an input to the constant-on-time PWM one-time one-shot circuit.

Thermal

Pad

GND

Signal Ground for The IC.
