MC34063 Datasheet – DC/DC Converter Control Circuit – Hotchip

Part Number: MC34063

Function : DC to DC Converter Controller

Package:  SOP 8, DIP 8 Pin type

Manufacturer: Hotchip Technology




The MC34063 is a monolithic control circuit containing the primary functions required for DC/DC converters. The device consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. This device is specifically designed to be incorporated in stepdown, step-up and voltage-inverting applications with a minimum number of external components.
