DESCRIPTION
The 34063C is a monolithic switching regulator control circuit containing the primary functions required for
DC-DC converters. This device consists of internal temperature compensated reference, voltage comparator,
controlled duty cycle oscillator with active current limit circuit, driver and high current output switch. The device
is specifically designed to be used in Step-Down, Step-Up and Voltage-Inverting applications with a minimum
number of external components.
The MC34063C is the enhanced version of MC34063A/B with the ability to work in higher frequency.
