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.
