AP34063 Rev. 3
UNIVERSAL DC/DC CONVERTER
Description
The AP34063 Series is a monolithic control circuit containing the
primary functions required for DC-to-DC converters. These
devices consist of an internal temperature compensated
reference, comparator, controlled duty cycle oscillator with an
active current limit circuit, driver and high current output switch.
This series is specifically designed for incorporating in
Step-Down and Step-Up and Voltage-Inverting applications with
a minimum number of external components.
