The Texas Instruments LM2576T-12/NOPB is a step-down switching regulator that provides a fixed 12V output from a 4V to 40V input. It is capable of delivering 3A of load current with excellent line and load regulation. The 52kHz switching frequency allows for small external components while maintaining high efficiency. Housed in a TO-220-5 package, it is easy to mount and heatsink. This converter is a reliable choice for applications requiring a simple, robust 12V power supply.
- Robust 4V-40V Input Range: Ensures stable operation under varying supply conditions, ideal for automotive and industrial use.
- 3A Output Current: Provides ample current for a wide range of loads without additional components.
- Fixed 52kHz Switching: Offers predictable EMI behavior and simplifies filter design.
- TO-220-5 Package: Standard package for easy thermal management and PCB layout.
Battery-Powered Devices
This buck converter efficiently steps down a 24V or 36V battery stack to a stable 12V rail for portable equipment. The 3A output supports motors, displays, and communication modules while maintaining high efficiency across the input range.
Automotive Power Systems
Designed for 12V automotive environments, the LM2576T-12/NOPB accepts 4V to 40V input, covering cranking and load-dump transients. It provides a regulated 12V supply for body electronics, sensors, and aftermarket accessories.
Industrial Automation
In factory settings, this converter steps down 24V control voltages to 12V for PLCs, relays, and actuators. Its 52kHz fixed frequency reduces interference with sensitive measurement equipment.
Telecom and Networking
For networking gear, the LM2576T-12/NOPB can generate a 12V local rail from a 48V backplane (with input derating). The simple external component count makes it easy to design into space-constrained line cards.
Distributed Power Architectures
Use this regulator as an intermediate bus converter to create a 12V distribution rail, which then feeds multiple point-of-load regulators. Its 3A capacity is sufficient for several downstream converters.
