The Texas Instruments LM2576HVSX-12/NOPB is a robust step-down switching regulator designed for high-voltage applications. It accepts a wide 4V to 60V input and delivers a fixed 12V output at up to 3A. Operating at a fixed 52kHz switching frequency, it provides a good balance between efficiency and external component size. The TO-263 (D2PAK) package ensures excellent power dissipation, making it suitable for industrial, automotive, and telecom power supplies.
- Wide Input Range (4V-60V): Handles automotive load dumps and industrial bus variations without external protection circuitry.
- High Output Current (3A): Supports demanding loads like motors, relays, and multiple logic rails from a single converter.
- Simple Fixed 12V Output: Eliminates the need for external feedback resistors, reducing BOM count and design complexity.
- Proven 52kHz Architecture: Offers reliable, low-EMI operation with mature, well-documented design guidelines.
- Robust TO-263 Package: Provides excellent thermal performance for continuous 3A operation in high-temperature environments.
Industrial Power Supplies
With a wide 60V input range and 3A output capability, this buck converter efficiently steps down unregulated industrial bus voltages (24V/48V) to a stable 12V rail for sensors, actuators, and control logic.
Automotive Battery Systems
Handling 4V to 60V input makes it ideal for 12V and 24V automotive systems, surviving load-dump transients while providing a regulated 12V supply for infotainment, telematics, and body control modules.
Networking Equipment
Routers and switches often require a 12V intermediate bus. The LM2576HVSX-12's 52kHz frequency and 3A current provide a reliable, low-noise solution for powering line cards and communication processors.
Telecom Base Stations
In remote radio units, the converter steps down 48V backhaul supplies to 12V for digital processing, leveraging its high input voltage tolerance and robust TO-263 package for thermal dissipation.
