AP3440 Datasheet 2mhz High Performance Synchronous Buck Converter

Manufacturer: Diodes Incorporated

Overview: NEW PRODUCT A Product Line of Diodes Incorporated AP3440 4A, 2MHZ HIGH PERFORMANCE SYNCHRONOUS BUCK.

General Description

The AP3440 is a current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 4A load with high efficiency, excellent line and load regulation.

The device integrates two N-channel power MOSFETs with low onresistance.

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