Product Summary

The MC33063AP1G is a 1.5 A, step-up/down/ inverting switching regulator. The MC33063AP1G consists of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. The MC33063AP1G was specifically designed to be incorporated in Step-Down and Step-Up and Voltage-Inverting applications with a minimum number of external components. Refer to Application Notes AN920A/D and AN954/D for additional design information.
