NCP3155A Product details

Description

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.The VIN pin is also connected to the internal power NMOS switch.It is also used in conjunction with the VSW pin to sense current in the high side MOSFET.The VIN pin has high dI/dt edges and must be
