APW7179 - 1A Synchronous Step-Down Converter

General Description

The APW7179 consists of two independent 1.5MHz constant frequency, current mode, and PWM step-down converters.

Each converter integrates a main switch with a synchronous rectifier for high efficiency without an external Schottky diode.
