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.
