DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'IM' corresponds to the 8-DIP package variant when sourcing. Confirm RoHS compliance status as required by your assembly specifications. Check for obsolescence notices or lifecycle changes from Microsemi or its successor entities prior to finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring low quiescent current during startup phases. Ensure the input voltage remains within the 7.6V to 30V operational window. Consider the 8-DIP package constraints for PCB layout and thermal management requirements compared to surface-mount alternatives.

DC DC Switching Controllers Part Context

The LX1553IM belongs to the LX155X series of power management integrated circuits. This family focuses on high-efficiency control for isolated and non-isolated power supplies. The IM designation specifically identifies the dual-in-line package version, distinguishing it from surface-mount options like the IDM variant.
