AP3211 Datasheet 1.5a Asynchronous DC-dc Buck Converter

Manufacturer: Diodes Incorporated

Overview: AP3211 1.4MHZ,1.5A ASYNCHRONOUS DC-DC BUCK CONVERTER.

General Description

The AP3211 is a 1.4MHz fixed frequency, current mode, PWM buck (step-down) DC-DC converter, capable of driving a 1.5A load with high efficiency, excellent line and load regulation.

The device integrates N-channel power MOSFET switch with low on-resistance.

Current mode control provides fast transient response and cycle-bycycle current limit.
