AP3406A - BCD Semiconductor

AP3406A 1.1MHz 800mA SYNCHRONOUS DC-DC BUCK CONVERTER

The AP3406A is a 1.1MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 800mA load with high efficiency, excellent line and load regulation. The device integrates a main switch and a synchronous switch without an external Schottky diode. It is ideal for powering portable equipment that runs from a single .
