LM2677SD-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2677SD-12 is a SIMPLE SWITCHER high-efficiency 5A step-down voltage regulator manufactured by Texas Instruments, formerly National Semiconductor. It operates with an input voltage range of 8V to 40V and provides a fixed 12V output at up to 5A. The device integrates a 0.44Ω N-channel power switch and operates at a switching frequency of 350kHz. It utilizes pulse-width modulation (PWM) control mode and is housed in a 14-pin VSON package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a low-on-resistance N-channel power switch for high efficiency
Features internal compensation for minimal external component count
Includes thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Distributed power architectures
Battery-powered equipment requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the suffix indicates the specific 12V fixed output variant. Ensure the package matches the 14-VSON specification. Check RoHS compliance status if required for your assembly process. Validate the part number against official TI databases to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an 8V to 40V input source. It is suitable for applications needing up to 5A continuous current. Consider the 350kHz switching frequency for balancing component size and efficiency. Ensure the thermal design supports the expected load and ambient temperature conditions within the -40°C to 125°C operating range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM267x family of SIMPLE SWITCHER regulators. It offers higher current capability compared to the 3A LM2676 series. The SD suffix denotes the VSON package type. It serves as a robust solution for medium-power DC-DC conversion needs in industrial and consumer electronics.
