## Summary description

The Texas Instruments LM2676S-5.0 is a fixed-output step-down (buck) switching regulator providing a 5 V output from an 8–40 V input range. Supplied in a TO-263-7 package, it is designed for efficient DC–DC conversion in power-supply modules, embedded systems, industrial controls and automotive electronics where regulation from higher voltages to stable 5 V is required.

## Long description

The Texas Instruments LM2676S-5.0 is a fixed-output step-down (buck) switching regulator that delivers a stable 5 V output from input voltages between 8 V and 40 V. Housed in a TO-263-7 surface-mount package, the device is intended for efficient DC–DC conversion where a regulated 5 V rail is required. The regulator integrates switching control and output stage components to simplify power-supply design and reduce external component count.
Advantages
The LM2676S-5.0 offers high-efficiency switching operation that reduces power dissipation compared with linear regulators when stepping down from higher input voltages. Its fixed 5 V output removes the need for external reference adjustment and simplifies board layout. The TO-263-7 package provides thermal performance suitable for many compact power modules, and the integrated control functions reduce the number of discrete parts needed for a complete regulator solution.
Suitable for
Embedded systems requiring a reliable 5 V supply
Industrial control electronics with higher supply voltages
Automotive electronics and subsystems where 12 V or 24 V must be converted to 5 V
Power-supply modules and DC–DC conversion boards
Key specifications
Output voltage: fixed 5.0 V
Input voltage range: 8 V to 40 V
Topology: step-down (buck) switching regulator
Package: TO-263-7 (surface-mount power package)
Integrated switching control and output stage for simplified external components
How to use
Place the LM2676S-5.0 on the PCB following the recommended footprint for the TO-263-7 package and route power and ground planes to optimize thermal dissipation. Select the inductor, diode, input and output capacitors according to the device application guidelines to achieve stable regulation and low output ripple. Connect the input supply (8–40 V) to the regulator input pin and take the regulated 5 V output from the output pin; observe correct polarity and layout best practices for switching regulators. Follow the manufacturer's application notes for recommended external component values, compensation and layout to ensure reliable operation.
Usage recommendations
For best thermal performance and minimum EMI, use recommended component values and layout practices from the device documentation. Provide adequate heat sinking or copper area on the PCB when operating near the upper limits of input voltage or output current, and include input filtering to protect against supply transients.
