5-A Peak Boost, Buck, Inverting Switching Regulator 1 Features •1 AEC-Q100 Qualified With the Following Results: – Device HBM ESD Classification Level 2 – Device CDM ESD Classification Level C4B • 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 Automotive: Buck, Boost, and Inverting Topologies 3 Description The MC33063A-Q1 device is an easy-to-use IC containing all the primary circuitry needed for building simple DC-DC converters.
The device primarily consists 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 requires minimal external components to build converters in the boost, buck, and inverting topologies.
The MC33063A-Q1 device is characterized for operation from –40°C to 125°C.
