DC-TO-DC CONVERTER CONTROL CIRCUITS
SL34063A
The SL34063A 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 and Step-Up and Voltage-Inverting applications with a minimum number of external
components.
