The MIC4575WU-TR from Microchip Technology is a flexible DC-DC converter supporting both Buck and Buck-Boost topologies. It operates from a 4V to 24V input and provides an adjustable output from 1.23V to 20V, with a switch current rating of 1.7A. The fixed 200kHz switching frequency allows for small external components while maintaining high efficiency. Housed in a TO-263-6 (D2PAK) package, it is suitable for automotive, industrial, and battery-powered applications requiring a wide input range and robust performance.
- Buck-Boost Flexibility: Can step up or step down voltage, simplifying designs where input varies around the output.
- Wide Input Range (4V-24V): Accommodates a variety of power sources, from batteries to industrial rails.
- 1.7A Switch Current: Supports moderate load requirements without external transistors.
- Fixed 200kHz Operation: Balances efficiency with component size, reducing EMI filtering needs.
- Robust D2PAK Package: Excellent thermal performance for high-power dissipation.
Battery-Powered Equipment
With 4V-24V input and buck-boost capability, it can regulate output from a battery whose voltage drops below the regulated level, maximizing usable battery capacity.
Automotive Electronics
The wide input range and 200kHz frequency make it suitable for powering sensors, actuators, and audio systems from a 12V vehicle bus.
Industrial Power Supplies
Provides a rugged, reliable solution for 5V, 12V, or adjustable rails in PLCs, motor controls, and test equipment.
Telecom and Networking
Can step down or step up to generate required rails from a 12V or 24V backplane, reducing the need for multiple converters.
Point-of-Load Regulation
Its buck-boost topology allows it to maintain a stable output even when the input voltage is close to or below the output voltage.
Portable Instruments
High efficiency and low quiescent current extend battery life in handheld meters and medical monitors.
