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.

Absolute Maximum Ratings (@TA = +25°C, unless otherwise specified.)
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to
absolute maximum rating conditions for extended periods of time.
