DC/DC Converter Controller

The FAC34063AP/AF 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 was specifically designed to

be incorporated in Step-Down or Step-Up or Voltage-Inverting

applications with a minimum number of external components.
