NCP3155A Overview
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 . 2 VIN The VIN pin powers the internal control circuitry and is monitored by an undervoltage parator. The VIN pin is also connected to the internal power NMOS switch.
