The LM2576HVS-12 is a high-voltage step-down (buck) DC-DC converter from UMW, delivering a fixed 12V output from inputs up to 57V. With a 3A current capability and a fixed 52kHz switching frequency, it offers a simple, reliable solution for powering 12V loads from higher-voltage sources. Its wide input range makes it particularly suited for industrial, automotive, and telecom environments where voltage transients are a concern. The TO-263-6 (D2PAK) package provides excellent heat dissipation for continuous operation.
- Wide Input Range (up to 57V): Directly handles 48V rails and 24V automotive transients without external protection.
- High 3A Output: Powers multiple 12V loads, including motors, fans, and lighting.
- Fixed 52kHz Switching: Enables compact, low-cost filter components and predictable EMI behavior.
- Robust TO-263 Package: Ensures low thermal resistance for reliable operation in high-temperature environments.
Industrial Motor Control
From a 48V industrial bus, the LM2576HVS-12 steps down to 12V to power motor drivers, relays, and solenoid valves, providing a stable and efficient supply for factory automation.
Automotive Lighting Systems
In 24V trucks and buses, this converter generates a regulated 12V rail for LED lighting modules, dashboard displays, and auxiliary power outlets, handling voltage spikes up to 57V.
Telecom Base Stations
Telecom equipment often uses 48V backplanes. This buck converter efficiently produces 12V for RF power amplifiers, baseband processors, and cooling fans.
Medical Device Power
For portable or bedside medical monitors operating from 24V adapters, the LM2576HVS-12 provides a clean 12V supply for sensors, pumps, and display backlights.
Robotics and Drones
High-capacity LiPo batteries (up to 12S, ~50V) can be stepped down to 12V for servos, flight controllers, and peripheral sensors, ensuring consistent performance.
Audio Equipment
Professional audio mixers and amplifiers with 48V phantom power rails can use this converter to derive a quiet 12V supply for analog circuits and DSPs.
