AP3406概述：600mA，1.1MHz同步降压DC/DC稳压器
The AP3406 is a 1.1MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 650mA load with high efficiency, excellent line and load regulation. The AP3406 integrates a main switch and a synchronous switch without an external Schottky diode. AP3406 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 AP3406. This feature greatly simplifies the design of switch-mode power supplies.
This AP3406 is available in TSOT-23-5 and SOT-23-5 packages.
