APW7093 - Anpec Electronics Coropration

APW7093 Step Down DC/DC Regulator

The APW7093 is a reversible energy flow, constantoff-time, pulse-width modulated (PWM), step-down DC-DC converter. It is ideal for use in notebook and sub-notebook computers that require 1.1V to 5V active termination power supplies. This device features an internal PMOS power switch and internal synchronous rectifier for high efficiency and reduced component.
