## Summary description

Fixed 12V DC/DC switching regulator Texas Instruments LM2576HVT-12/NOPB in TO-220-5 package. This PMIC provides a regulated 12V output using a switching topology for efficient voltage conversion in power supply designs. Suitable for embedded systems, industrial electronics and DIY power modules where a reliable 12V rail is required. Through-hole TO-220-5 mounting simplifies board assembly and heat dissipation.

## Long description

The DC/DC Switching Regulator Texas Instruments LM2576HVT-12/NOPB is a fixed 12V output switching regulator supplied in a through-hole TO-220-5 package. Designed for efficient step-down voltage conversion, this power management IC delivers a regulated 12V rail using switching topology to minimize heat dissipation and maximize conversion efficiency. The TO-220-5 form factor provides easy mounting and improved thermal performance for medium-power applications where a stable 12V supply is required.
Advantages
The LM2576HVT-12/NOPB offers a fixed 12V output with switching regulation to reduce power loss compared with linear regulators, enabling higher efficiency in power supply designs. The TO-220-5 through-hole package simplifies PCB assembly and provides a convenient path for heat sinking. The device is suitable for designs that require a robust, continuous 12V output and includes internal switch and control circuitry to reduce component count in typical converter implementations.
Suitable for
 Embedded systems and microcontroller boards requiring a regulated 12V rail
 Industrial control electronics and automation modules
 DIY power modules and hobbyist power supplies
 Point-of-load supplies for sensors, relays, and actuators
 Replacement or retrofit in through‑hole 12V regulator circuits
Key specifications
 Output voltage: Fixed 12V regulated output
 Regulation topology: Buck (step-down) switching regulator
 Package type: Through-hole TO-220-5
 Cooling: Enhanced heat dissipation via tab and heatsink mounting
 Typical application power range: medium-power DC/DC conversion (refer to manufacturer datasheet for exact current limits)
How to use
Implement the LM2576HVT-12/NOPB on a PCB using the TO-220-5 footprint and secure the package to a heatsink or PCB copper area to manage thermal load. Follow the manufacturer’s recommended external components for inductor, diode, input and output capacitors to ensure stable operation and minimize output ripple. Apply an appropriate input voltage higher than the 12V output (within the device input range specified in the datasheet) and verify correct wiring of ground, input, output and feedback connections. Observe polarity and grounding best practices during assembly and testing.
Usage recommendations
For reliable performance, pair the regulator with low-ESR capacitors on the input and output, choose an inductor rated for the expected current with appropriate saturation characteristics, and use a fast-recovery or Schottky diode as recommended by Texas Instruments. Provide adequate heatsinking when operating near maximum current or in elevated ambient temperatures, and consult the official datasheet for thermal, input-voltage, and output-current limits before finalizing designs.
