General Description

The AP3422 contains two independent 1.1MHz fixed

frequency, current mode, PWM synchronous buck

(step-down) DC-DC converters, each of them is

capable of driving a 800mA load with high efficiency,

excellent line and load regulation. Each converter

integrates a main switch and a synchronous switch

without an external Schottky diode. It is ideal for

powering portable equipment that runs from a single

Li-ion battery.

A standard series of inductors are available from

several different manufacturers optimized for use

with the AP3422. This feature greatly simplifies the

design of switch-mode power supplies.

This IC is available in DFN-3×3-10 package.
