NCP5230MNTWG (ON SEMICONDUCTOR)

The NCP5230MNTWG is a precise low voltage synchronous buck controller with power saving mode in 16 pin QFN package. It is a simple single phase solution with differential phase current sensing, 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 system. The NCP5230 also features soft start sequence, accurate overvoltage and overcurrent protection, UVLO for VCC and VCCP, thermal shutdown, chip enable through OSC pin, latched overvoltage protection (OVP), internally fixed OCP threshold and start-up into pre-charged loads. Automatic power saving mode to maximize efficiency during light load operation. It has VCC voltage range from 4.5V to 13.2V and operating current of 5mA (VCC = 5V, EN = high).
