BCD Semiconductor Manufacturing Limited
General Description
The AP3003 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 include internal frequency com-
pensation and a fixed frequency oscillator so that they
are easy to use. A system adopting AP3003 requires a
minimum number of external components to work.
A standard series of inductors, optimized for use with
the AP3003 series, are available from several manu-
facturers. This feature greatly simplifies the design of
switch-mode power supplies.
These ICs are available in TO-220-5 and TO-263-5
packages.
