Dual 1.3MHz, 800mA Synchronous Step-Down Converter

The APW7139 consists of two independent 1.3MHz 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. The APW7139 is ideal for powering portable equipment that runs f
