MC33063A-Q1 (ACTIVE) Automotive Catalog 1.5-A Peak Boost/Buck/Inverting Switching Regulator

 

Description

The MC33063A-Q1 device is an easy-to-use IC containing all the primary circuitry needed for building simple DC-DC converters. The device 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 device requires minimal external components to build converters in the boost, buck, and inverting topologies.

The MC33063A-Q1 device is characterized for operation from –40°C to 125°C.
