The MIC4574YN from Microchip Technology is a versatile Buck DC-DC converter designed for medium-power step-down applications. It accepts an input voltage from 4V to 24V and provides an adjustable output from 1.23V to 20V, delivering up to 500mA. Operating at 200kHz, it offers a good balance between efficiency and external component size. The 8-DIP package is ideal for through-hole assembly and prototyping. This converter is well-suited for battery-powered devices, industrial controls, and embedded systems.
- Adjustable Output: Output can be set from 1.23V to 20V, providing design flexibility.
- Wide Input Range: Accepts 4V to 24V, compatible with many common supply rails.
- Through-Hole Package: 8-DIP package simplifies prototyping and manual assembly.
- Reliable Performance: 200kHz switching ensures stable operation with standard components.
Battery-Powered Equipment
With a 4V to 24V input range, the MIC4574YN efficiently steps down battery voltages to regulated levels. The 500mA output is ideal for portable instruments and handheld tools.
Distributed Power Systems
In multi-rail systems, this converter provides a clean, adjustable output from a higher intermediate bus. The 200kHz frequency balances efficiency and component size.
Industrial Sensors and Actuators
For 12V or 24V industrial loops, the MIC4574YN generates lower voltages for microcontrollers and signal conditioning circuits. Its through-hole DIP package is easy to prototype and service.
Consumer Electronics
In set-top boxes and gaming peripherals, this buck converter regulates 5V or 12V inputs down to logic levels. The adjustable output allows for custom voltage rails.
Telecom Line Cards
For -48V telecom systems, a front-end converter can create a 12V bus, which the MIC4574YN steps down to 5V or 3.3V for line card logic.
Embedded Systems
In microcontroller-based designs, this converter provides a stable core supply from a variety of input sources, ensuring reliable operation across different power conditions.
