MC34063A

1.5 A, Step-Up/Down/Inverting Switching Regulators

DESCRIPTION

The MC34063A 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 and Step–Up and Voltage–Inverting applications with a minimum number

of external components.
