NCP3155A Datasheet (ON Semiconductor) - 3A Synchronous Buck Regulator

NCP3155A, 3A Synchronous Buck Regulator

Pin Pin Name Description 1 PGND The PGND pin is the high current ground pin for the lower MOSFET and drivers which should be soldered to a large copper area to reduce thermal resistance.

2 VIN The VIN pin powers the internal control circuitry and is monitored by an undervoltage comparator.
