Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '1' indicates the 1.63A variant distinct from the standard LM5158. Confirm AEC-Q100 certification status for your target application. Ensure the WQFN-16 package thermal requirements are met in the final design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution requires high input voltage tolerance up to 60V. The 1.63A current limit suits moderate power applications where size constraints necessitate high-frequency operation. Consider the 16-pin QFN package for space-limited PCB layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM5158x family designed for wide input voltage ranges. The LM51581 variant specifically offers reduced current capacity compared to the LM5158 while maintaining identical voltage ratings and control features. Both share the same pinout and control architecture.
