Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' indicates tape-and-reel packaging when ordering. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence as per manufacturer specifications. Cross-reference the full part number against official Texas Instruments documentation to ensure compatibility with your design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required without external feedback resistors. The 600 mA current rating suits low-to-medium power loads. Ensure the application environment stays within the -30°C to +85°C operational limits. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3676 series of switching voltage regulators. It is functionally similar to the LM3676SD-1.8/NOPB but differs in packaging format, with the SDX variant typically supplied in reel packaging. It serves as a compact power solution within Texas Instruments' PMIC portfolio for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM3676SD-1.8/NOPB is a direct functional equivalent with identical electrical parameters but may differ in shipping packaging. Verify pinout compatibility and thermal performance characteristics between the SD and SDX variants during integration.
