Product Summary

The 34063API is a monolithic control circuit containing the primary function required for DC-to-DC converter. The 34063API is a 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.
