DNP015 Overview
Description
The DNP015 is a next-generation, Green Mode Fairchild Power Switch (FPS™) that incorporates Fairchild’s innovative mWSaver™ technology, which dramatically reduces standby and no-load power consumption, enabling conformance to all worldwide Standby Mode efficiency guidelines. It integrates an advanced current-mode pulse width modulator (PWM) and an avalanche-rugged 700 V SenseFET in a single package, allowing auxiliary power designs with higher standby efficiency, reduced size, improved reliability, and lower system cost than prior solutions.
