LED Driver IC Procurement Notes

Verify the specific suffix 'HV' confirms the extended 65V input rating required for your application, as standard variants may differ. Ensure the HTSSOP-24 package footprint matches your PCB layout. Confirm AEC-Q100 qualification status aligns with your vehicle's reliability requirements before finalizing the design.

LED Driver IC Selection Notes

Select this component when designing high-voltage automotive LED circuits requiring dual-channel independence. The wide input voltage range accommodates various automotive bus conditions. Consider the 2MHz maximum switching frequency for inductor size optimization. Verify that the 5A per channel output capability meets the total luminous flux requirements of the target LED array.

LED Driver IC Part Context

This part belongs to the TPS92518HV family of dual buck LED controllers from Texas Instruments. It is specifically engineered for automotive environments, distinguishing itself from general-purpose industrial controllers through its extended voltage handling and robust thermal management capabilities integrated into the 24-pin PowerTSSOP package.

LED Driver IC Replacement Considerations

The TPS92518QPWPRQ1 is a related variant but typically supports lower input voltages (up to 42V). Do not substitute directly if the application requires operation above 42V without verifying the specific HV rating.
