Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SD' corresponds to the WSON-10 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering part number matches the required tape and reel or cut tape configuration. Cross-reference the datasheet revision to validate thermal and electrical parameters against your design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a 2 A output current from a wide input voltage range. The 2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the WSON-10 package constraints for PCB layout and thermal dissipation. Evaluate the need for frequency synchronization if multiple converters operate in close proximity.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM27342 family of wide-input-range synchronous buck regulators. It shares core architectural features with other members like the LM27342MY/NOPB, differing primarily in the physical package type. The SD suffix specifically denotes the WSON-10 footprint, distinguishing it from MSOP or HVSSOP variants within the same functional family.
