SLLS636N – DECEMBER 2004 – REVISED JANUARY 2015 MC3x063A 1.5-A Peak Boost/Buck/Inverting Switching Regulators
1 Features 3 Description The MC33063A and MC34063A devices are easy-touse ICs containing all the primary circuitry needed for
building simple DC-DC converters. These devices
primarily consist of an internal temperaturecompensated 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. 1 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 2 Applications The MC33063A device is characterized for operation
from –40°C to 85°C, while the MC34063A device is
characterized for operation from 0В°C to 70В°C. Blood Gas Analyzers: Portable …
