DC-TO-DC CONVERTER CONTROL CIRCUITS

The IL34063Ais 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.
