LM2676SD-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676SD-12 is a SIMPLE SWITCHER step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 8V to 40V and provides a fixed 12V output at up to 3A. The device utilizes a 260kHz switching frequency and employs pulse width modulation control. It is housed in a 14-pin LLP package, suitable for surface mount applications within a temperature range of -40°C to 125°C.

• Integrated high-current switch capable of delivering 3A load current
• Fixed 12V output configuration simplifies design implementation
• Operates from standard 12V or 24V input sources

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Input conditioning for microprocessors and FPGAs
• Battery-powered equipment requiring stable 12V supply

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and electrical characteristics. Ensure the component matches the required thermal performance and pinout for the target PCB layout. Cross-reference manufacturer documentation to validate authenticity and revision status before integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from inputs between 8V and 40V. It is appropriate for designs prioritizing low external component count and moderate efficiency over synchronous rectification benefits. Consider thermal management requirements due to the non-synchronous topology and power dissipation at higher loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2676 family of SIMPLE SWITCHER regulators. These devices are designed to reduce external component count while maintaining high efficiency. The SD variant specifically denotes the LLP package format, distinguishing it from TO-263 or VSON options within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2676SD-12/NOPB is the lead-free version of this component. Verify compatibility with RoHS directives if environmental compliance is required for the final assembly.
