Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status prior to ordering. Ensure the package designation matches the required VQFN-HR-12 thermal characteristics. Confirm that the 2.1 MHz switching frequency aligns with EMI requirements for the target application. Validate input voltage ranges against the actual supply rail conditions to prevent overvoltage stress.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when high input voltages up to 60 V are present alongside strict size constraints. The 1.5 A current rating suits moderate load requirements without excessive heatsinking. The 2.1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the -40°C to +150°C operating range for harsh automotive thermal environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR36015 family of ultra-small synchronous step-down converters. It shares architectural similarities with other members like the LMR36006 but offers higher current capacity. The series is optimized for automotive electronics requiring small footprints and wide input voltage tolerance.
