The MIC4575WT from Microchip Technology is a versatile, simple-to-use step-down switching regulator. It accepts a wide input voltage from 4V to 24V and can deliver up to 1.7A to the load. The output voltage is adjustable from 1.23V to 20V. It can also be configured as a buck-boost (inverting) regulator. Operating at a fixed 200kHz, it offers a good balance of efficiency and external component size. This regulator is ideal for industrial, automotive, and battery-powered applications.
- Wide Input Voltage Range: Operates from 4V to 24V, covering a broad range of power sources.
- Flexible Topology: Can be used as a Buck or Buck-Boost (inverting) converter, increasing design flexibility.
- Simple and Robust: The TO-220 package is easy to heatsink and handle in through-hole designs.
- Proven Technology: Based on a mature, reliable switching regulator architecture.
Industrial Power Supplies
The wide 4V to 24V input range and 1.7A output make it suitable for industrial control circuits, sensors, and actuators powered from 12V or 24V rails.
Automotive Aftermarket Electronics
It can step down 12V automotive battery voltage to power aftermarket audio systems, LED lighting, and USB chargers.
Negative Voltage Generation
In Buck-Boost (inverting) configuration, it can generate a negative supply rail (e.g., -5V) from a positive input, useful for op-amp circuits and LCD bias supplies.
Battery-Powered Equipment
For systems using 4 to 8 NiMH or Li-ion cells, this converter provides a regulated output for motors, displays, and microcontrollers.
Distributed Power Systems
It can be used as a simple, cost-effective POL converter in systems with a 24V intermediate bus, providing a regulated 5V or 3.3V rail.
