MC34063
Description
The MC34063 is a monolithic control circuit containing the primary functions required for DC/DC converters. The device consists of an internal temperature pensated reference, parator, 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 ponents. The ±2% internal reference and low quiescent current of 1.6m A are among the improvements of the device over the petition
