Product Overview

The MC33063AD is a boost/buck/inverting switching regulator in 8 pin SOIC package. It is an easy to use regulator containing all primary circuitry needed for building simple DC to DC converters. The MC33063AD regulator primarily consist of an internal temperature compensated reference, comparator, oscillator, PWM controller with active current limiting, driver and high current output switch. This device requires minimal external components to build converters in boost, buck and inverting topologies.
  • Adjustable output voltage range from 1.25V to 40V
  • Wide input voltage range from 3V to 40V
  • High output switch current up to 1.5A
  • Oscillator frequency up to 100KHz
  • Precision internal reference is 2%
  • Short circuit current limiting
  • Low standby current
  • Operating temperature range -40°C to 85°C
