1.1MHz, 650mA SYNCHRONOUS DC-DC BUCK CONVERTER
AP3406
Description
Parametric Table
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 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.
