Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XSD' corresponds to the 6-WSON package configuration during procurement. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per manufacturer standards. Ensure ordering quantities align with standard reel sizes to avoid additional handling fees associated with cut tape or mouse reel packaging options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring both boost and SEPIC capabilities within a minimal footprint. The 1.6MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 2.1A switch current limit against peak load requirements to ensure adequate headroom. Evaluate thermal performance given the small WSON package dimensions under maximum load conditions.
