MC33063ADRJR Datasheet

DC/DC Switching Regulators


The MC33063ADRJR and MC34063A are easy-to-use ICs containing all the primary circuitry needed for building simple dc-dc converters. These devices primarily consist 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 devices require minimal external components to build converters in the boost, buck, and inverting topologies.The MC33063ADRJR is characterized for operation from –40°C to 85°C, while the MC34063A is characterized for operation from 0°C to 70°C. MC33063ADRJR Features • Wide Input Voltage Range: 3 V to 40 V• High Output Switch Current: Up to 1.5 A• Adjustable Output Voltage• Oscillator Frequency Up to 100 kHz• Precision Internal Reference: 2%• Short-Circuit Current Limiting• Low Standby Current
