General Description

The AP3407/A is a 1.4MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 1.2A load with high efficiency, excellent line and load regulation.

The device integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance.

It is ideal for powering portable equipment that runs from a single Li-ion battery.
