Description
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.
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 IC is available in TSOT-23-5 and SOT-23-5
packages.
