MC33063A Step-Up / Down / Inverting Switching Regulator, 1.5 A
Item # 1479
SMD    MC33063
MC33063A  1.5-A  Boost / Buck / Inverting Switching DC-DC Converter
Package type: SO 8-pin
Description: The MC33063A device is easy-to-use IC 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 device require minimal external components to build converters in the boost, buck, and inverting topologies.
• 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

The ONLY difference between MC33063A and MC34063A:
The MC33063A device is characterized for operation from –40°C to 85°C, while the MC34063A device is characterized for operation from 0°C to 70°C.
