The UMW LM2575HVS-12 is a simple, high-voltage Buck DC-DC converter that accepts inputs up to 57V and provides a fixed 12V output at up to 2A. With a 150kHz switching frequency, it offers a good balance between efficiency and component size. The TO-263-6 (D2PAK) package ensures excellent thermal performance, making it suitable for automotive, industrial, and telecom applications.
- High Input Voltage: Handles up to 57V, ideal for 48V systems and automotive load-dump conditions.
- Simple Fixed Output: The 12V fixed output requires minimal external components, simplifying design and BOM.
- Robust Package: The TO-263-6 D2PAK package provides excellent heat dissipation for 2A continuous operation.
- Proven Technology: Based on the industry-standard LM2575 architecture, ensuring reliability and availability.
Automotive 12V Systems
The LM2575HVS-12 can step down a 24V or 48V truck battery to a regulated 12V for auxiliary loads, with the 57V input rating providing margin for voltage spikes.
Industrial Control Panels
In factories with 48V DC buses, this converter provides a stable 12V rail for PLCs, relays, and sensors, simplifying power distribution and reducing heat generation.
Telecom Base Stations
For -48V telecom supplies, the LM2575HVS-12 can generate a 12V local rail for fans, control logic, and monitoring circuits, with the D2PAK package handling thermal dissipation.
HVAC and Building Automation
In commercial HVAC systems, 24V AC is often rectified to ~34V DC. This buck converter steps that down to 12V for controllers, actuators, and communication modules.
Solar-Powered Remote Systems
Solar panels can produce 30-50V open-circuit voltage. The LM2575HVS-12 regulates this to 12V for battery charging or direct loads in remote monitoring stations.
Electric Vehicle Charging Stations
Charging stations often have high-voltage DC buses. This converter can provide a 12V auxiliary supply for control boards, displays, and communication interfaces.
