LED Driver IC Procurement Notes

Verify the specific suffix 'H' versus standard designation when sourcing, as datasheet references often cite TPS923655HMDMTR. Confirm RoHS compliance status through official manufacturer documentation. Ensure the VSON-14 package footprint matches your PCB layout requirements before finalizing procurement decisions.

LED Driver IC Selection Notes

Select this component for designs requiring high input voltage tolerance up to 65 V. The integrated switch simplifies bill of materials by eliminating external MOSFETs. Consider the wide operating temperature range for harsh environments. Verify that the required dimming method aligns with the supported analog, hybrid, or PWM options.

LED Driver IC Part Context

This part belongs to the TPS923655 series of single-channel LED drivers. It shares architectural similarities with the TPS923654 but may differ in specific qualification or packaging details. It serves as a solution for driving high-power LEDs in boost or buck-boost topologies without synchronous rectification.

LED Driver IC Replacement Considerations
