Dual 1.3MHz, 800mA Synchronous Step-Down Converter

The APW7139 consists of two independent 1.3MHz con- stant frequency, current mode, 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 from a single cell Lithium-Ion (Li+) battery. Each converter CAN sup- ply 800mA of load current from a 2.5V to 5.5V input voltage. The output voltage CAN be regulated as low as 0.6V. The APW7139 CAN also run at 100% duty cycle for low dropout applications. By Anpec Electronics Corporation
