AP3440 Datasheet (Diodes Incorporated) - 2MHZ HIGH PERFORMANCE SYNCHRONOUS BUCK CONVERTER

AP3440, 2MHZ HIGH PERFORMANCE SYNCHRONOUS BUCK CONVERTER

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 cy
