Description Power supply for MOSFET drivers Bottom gate MOSFET driver pin.

The NCP81031 is a simple single phase solution with differential phase current sensing, low current power saving mode of operation, and on board gate drivers to provide accurately regulated power. It can be set up to synchronize to an external clock or PWM signal within certain frequency range. The adaptive non overlap gate drive and power saving operation circuit provide a low switching loss and high efficiency solution for server, notebook, and desktop systems. A high performance operational e.
