Preliminary Datasheet
380kHz, 2A Asynchronous DC-DC Buck Converter
AP3202
General Description
The AP3202 is a 380kHz fixed frequency, current
mode, PWM buck (step-down) DC-DC converter,
capable of driving a 2A load with high efficiency,
excellent line and load regulation. The device
integrates N-channel power MOSFET switch with
low on-resistance. Current mode control provides fast
transient response and cycle-by-cycle current limit.
A standard series of inductors are available from
several different manufacturers optimized for use
with the AP3202. This feature greatly simplifies the
design of switch-mode power supplies.
This IC is available in SOIC-8 package.
