Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification and 'MY' denotes the HVSSOP-10 package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified thermal performance requirements for the chosen enclosure type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when automotive reliability and external clock synchronization are required. Compare against non-qualified variants if industrial or consumer applications suffice. Evaluate thermal dissipation needs based on the 1.5 A continuous load capability and the specific PCB copper area available for heat spreading in the HVSSOP-10 footprint.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM27341 family of wide input synchronous buck regulators. It shares core electrical characteristics with other package options like the SD (WSON) variant but differs in physical dimensions and thermal properties. The Q-series designation specifically targets automotive markets, distinguishing it from standard commercial grade counterparts within the same functional family.
