AP3418 Datasheet 1.4mhz High Efficiency Synchronous DC-dc Buck Converter

Manufacturer: Diodes Incorporated

Overview: A Product Line of Diodes Incorporated AP3418 1.5A, 1.4MHZ HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK.

General Description

Pin Assignments The AP3418 is a 1.4MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 1.5A 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.
