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.
