Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix J7001886 against official Texas Instruments documentation to confirm pinout and electrical specifications match standard LM2676SX-ADJ parameters. Ensure compatibility with your PCB footprint, specifically the TO-263-8 D2PAK package dimensions. Confirm that the supplier provides traceability data and original manufacturer packaging to guarantee component authenticity and reliability for your specific application requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 260kHz frequency is required to simplify external inductor and capacitor selection. It is suitable for designs needing an adjustable output up to 37V with a maximum load current of 3A. Consider the TO-263 package for applications where moderate heat dissipation is needed without active cooling. Compare against other SIMPLE SWITCHER devices if higher current or different input voltage ranges are necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2676 series of SIMPLE SWITCHER regulators, designed for high-efficiency step-down applications. It complements other variants like the LM2676SX-12/NOPB but offers adjustable output flexibility. The series is known for integrating power switches and control logic into a single IC, reducing component count and board space compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2676SX-ADJ/NOPB and LM2676SX-ADJ from Texas Instruments. Verify pin compatibility and thermal characteristics before substitution. Alternative families may require redesign of feedback networks due to different reference voltages or switching frequencies.
