Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2676SX-ADJ/NOPB

LM2676SX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676SX-ADJ/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage between 1.2V and 37V. The device features a fixed switching frequency of 260kHz, enabling the use of small external components. It delivers up to 3A of output current and includes internal thermal shutdown and current limiting for robust protection. The component is housed in a TO-263-7 (D2PAK) surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck converter topology for efficient step-down regulation
Adjustable output voltage capability via external resistor network
Built-in thermal overload and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient voltage conversion
Industrial control power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS adherence. Confirm the ADJ designation matches the required adjustable output configuration rather than a fixed voltage variant. Ensure the TO-263-7 package type aligns with the target PCB footprint and thermal management strategy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 40V must be stepped down to an adjustable level with currents up to 3A. The 260kHz switching frequency allows for compact passive component selection compared to lower-frequency alternatives. Consider the thermal performance of the D2PAK package for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2676 series of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion. It serves as a versatile solution for applications requiring a single output channel with adjustable voltage settings, distinguishing it from fixed-output variants within the same family.
