Product Summary
The MC34063ADR is a 1.5A peak boost/buck/inverting switching regulator. It contains all the primary circuitry needed for building simple dc-dc converters. The MC34063ADR primarily consists of an internal temperature-compensated reference, a comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch; thus, the MC34063ADR requires minimal external components to build converters in the boost, buck, and inverting topologies.
