MC34063D
DESCRIPTION
The MC34063D is a monolithic control circuit containing the primary functions required for DC-to-DC converter. This device consist of an internal temperature pensated reference, parator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. Employing a minimum number of external ponents, the MC34063D is designed for Step-Down, Step-Up and Voltage-Inverting applications.
