Preliminary Datasheet
150kHz 3A PWM BUCK DC-DC CONVERTER
General Description
Features
AP3001
The AP3001 series of regulators are fixed frequency
PWM buck (step-down) DC/DC converter, capable of
driving a 3A load with excellent line and load regula-
tion. These regulators are simple to use and include
internal frequency compensation and a fixed frequency
oscillator, so that a system adopting AP3001 requires a
minimum number of external components to work.
These ICs are available in TO-220-5L, TO-220B-5L
and TO-263-5L packages.
