DESCRIPTION
The MC34063C is a monolithic switching regulator control circuit containing the primary funtion
required for DC-DC converters.
This device consists of internal temperature compenssated reference, voltage comparator, cotr
duty cycle oscillator with active current. The device is specifically designed to be used in Step-
Step-Up and Voltage-Inverting applications with a minimum number of external components.
The MC34063C is the enhanced version of MC34063A with the ability to work in higher frequen
The 34063C is available in 2 pcakages : SOP-8 and DIP-8.
