Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix MNY corresponds to the TDFN-8 package and reel/cut tape availability as listed in official Microchip documentation. Confirm AEC-Q100 Grade 1 qualification status for automotive deployment requirements. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your design specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a non-synchronous boost topology is suitable for cost-sensitive designs requiring moderate efficiency up to 92%. It is appropriate for applications needing a wide input voltage range starting from 2.4 V. Consider the 500 kHz fixed frequency for passive component sizing. Evaluate the 1.8 A peak current limit against maximum load demands. Verify that the TDFN-8 thermal performance meets the system's heat dissipation needs without additional heatsinking.
