Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'GUR' corresponds to the tape-and-reel packaging format on official Texas Instruments ordering information. Confirm that the WSON-8 package dimensions match your PCB footprint requirements. Ensure compatibility with the 1MHz switching frequency for your filter design. Cross-reference the RoHS status and lead-free specifications against your assembly standards before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 120V is required alongside a compact solution. It is suitable for designs needing an integrated isolated supply via Fly-Buck functionality without additional controllers. Consider the 650mA output limit and 1MHz frequency for thermal management and passive component sizing. Verify that the 8-WSON package fits within the available board space constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM516x family of synchronous buck converters. It shares architectural similarities with the LM5168 but offers higher current capability. The series is targeted at high-voltage industrial and automotive markets. It integrates protection features typical of Texas Instruments' high-performance PMIC portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
