The Microchip Technology LM2575-12YN is a simple step-down DC-DC converter that provides a fixed 12V output from a 4V to 40V input. It can deliver up to 1A of load current with a switching frequency of 52kHz. The device is available in a 16-DIP package, making it suitable for through-hole assembly and prototyping. Its wide input range and robust design make it a reliable choice for industrial and automotive applications.
- Wide Input Range: 4V to 40V input handles automotive and industrial voltage variations.
- Simple Design: Requires only a few external components, simplifying PCB layout.
- Robust Protection: Includes thermal shutdown and current limiting for reliable operation.
- Through-Hole Package: 16-DIP package is easy to solder and replace in legacy designs.
Automotive Power Supplies
Regulates 12V from a 24V truck battery or 12V bus with transients up to 40V. The wide input range handles load-dump conditions.
Industrial Control Systems
Provides a stable 12V rail for PLCs, motor controllers, and sensors from 24V or 48V supplies. The 1A output is sufficient for logic and small actuators.
Telecom Equipment
Converts 48V telecom buses down to 12V for line cards and routers. The simple design requires minimal external components.
Battery Chargers
Used as a pre-regulator for 12V lead-acid or Li-Ion battery charging circuits. The 52kHz frequency reduces audible noise.
HVAC Systems
Powers control boards and valve actuators from 24V AC/DC supplies. The robust design withstands voltage spikes.
Test and Measurement
Provides a clean 12V supply for bench instruments and data acquisition systems. The through-hole DIP package is easy to prototype.
