Description

General part information

NCP81147 Series

The NCP81147 is a single phase solution with differential phase current sensing, synchronization input, remote ground power saving operation, and gate drivers to provide accurately regulated power. 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 error amplifier is provided to simplify compensation of the system. The NCP81147 features also include softstart sequence, accurate overvoltage and over current protection, UVLO for power supply rails, and thermal shutdown.
