APW7199 Overview
The APW7199 is a single-phase, constant-on-time, and synchronous P WM controller, which drives N-channel MOSFETs. An internal 0.5V temperature-pensated reference voltage with high accuracy is designed to meet the requirement of low output voltage applications. The APW7199 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook puters.
