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.
Features
• High Efficiency: up to 95%
• Output Current: 800mA
