LED Driver IC Procurement Notes

Verify the specific suffix 'DGQT' indicates the tape-and-reel packaging variant when ordering. Confirm that the application circuitry matches the 4.5 V to 60 V input requirements. Ensure thermal management solutions are adequate for the intended operating environment given the 125°C maximum junction temperature rating. Cross-reference the exact part number with official Texas Instruments documentation to ensure compatibility with existing designs.

LED Driver IC Selection Notes

Select this component for designs requiring a single-channel buck topology with up to 1.5 A output current. It is suitable for applications needing wide input voltage tolerance up to 60 V. Consider the adjustable frequency range for optimizing external component size and efficiency. Verify that the required dimming method aligns with the supported analog or PWM interfaces.

LED Driver IC Part Context

This device belongs to the TPS9251xHV family of high-voltage LED drivers. It shares functional similarities with the TPS92512 and TPS92513 models but differs in specific current ratings and feature sets. The HV designation indicates high-voltage capability, distinguishing it from standard voltage variants within the broader LED driver portfolio.

LED Driver IC Replacement Considerations

Check for direct pin-to-pin replacements such as the TPS92513HVDGQR if reel quantity preferences differ. Evaluate the TPS92512 series for higher current requirements. Verify electrical parameters against datasheets before substitution.
