Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AP' confirms the automotive grade and pin-compatible variant requirements. Ensure the VQFN-HR package thermal characteristics match the PCB layout design. Confirm AEC-Q100 certification documentation is available for quality assurance audits. Validate that the 2.1 MHz frequency aligns with EMI constraints in the target application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when automotive reliability is mandatory and space constraints require a high-frequency solution. The 2 A current capability suits moderate load applications where efficiency and thermal management are critical. Compare against lower current variants if load demands are below 2 A or higher current options if loads exceed this limit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR336x0AP-Q1 family of Simple Switcher converters designed specifically for automotive electronics. It shares architectural similarities with other members like the LMR33630AP-Q1 but differs in current rating and switching frequency specifications. The family targets robust power management in harsh automotive electrical environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR33620APAQRNXT is the commercial grade equivalent with identical electrical performance but lacks automotive qualification. LMR33630APAQRNXRQ1 offers higher current capacity but operates at a different switching frequency, requiring circuit redesign.
