MC34063A MC33063A DC-to-DC Converter Control Circuits
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 pensated reference, parator, 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 ponents. Refer to Application Notes AN920A/D and AN954/D for additional design information.
