General 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.
