Data Sheet 1.1MHz, 800mA SYNCHRONOUS DC-DC BUCK CONVERTER AP3406A General Description 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 Li-ion battery. A standard series of inductors are available from several different manufacturers optimized for use with the AP3406A. This feature greatly simplifies the design of switch-mode power supplies. This IC is available in TSOT-23-5, MSOP-10 and DFN-2×2-6(1) packages.
