Ensure the package type matches the required 16-lead HTSSOP footprint for PCB layout compatibility before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 4A synchronous buck solution is required for automotive or industrial environments. It is suitable for designs needing a 1MHz switching frequency to minimize passive component size. Verify that the input voltage stays within the 2.95V to 5.5V range and that the thermal design supports the specified junction temperature limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2012x series of PowerWise synchronous buck regulators. It shares architectural similarities with other members like the LM20136 but differs in maximum output current capabilities. The series is designed to meet stringent automotive reliability standards while providing efficient power management for low-voltage digital loads.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM20136MHE/NOPB is a related device in the same family offering higher current capacity. Verify if the increased current rating fits the thermal constraints. No direct pin-to-pin substitutes are confirmed in public documentation; consult official TI resources for cross-reference validation.
