DC-TO-DC CONVERTER CONTROL CIRCUITS
The 34063A is a monolithic control circuit containing the primary functions required for DC-to-DC converters.
These devices consist of an internal temperature compensated reference, comparator, 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 components.
