AP3503 Datasheet 340khz 3a Synchronous DC-dc Buck Converter

Manufacturer: Diodes Incorporated

Overview: AP3503 340kHZ 3A SYNCHRONOUS DC-DC BUCK CONVERTER.

General Description

The AP3503 is a 340kHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 3A load with high efficiency, excellent line and load regulation.

The device integrates N-channel power MOSFET switches with low onresistance.

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