TECHNICAL DATA

DC-TO-DC CONVERTER CONTROL CIRCUITS

IL34063A

The IL34063A 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.
