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
