Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging format for the target design. Cross-reference the manufacturer datasheet for accurate ordering information and environmental compliance details before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring a compact solution for driving LEDs with high input voltages. The integrated control loop simplifies design compared to discrete solutions. Consider the available switching frequencies to optimize external component size while maintaining efficiency requirements for the specific application environment.

Part Context

This part belongs to the TPS923650 series of LED drivers manufactured by Texas Instruments. It is distinct from evaluation modules like the TPS923650D1DSGREVM, which are used for testing rather than production. The series targets general illumination applications requiring reliable constant current drive in a small footprint.

Replacement Considerations

Consult the manufacturer's cross-reference tools for verified substitutes. Ensure any replacement maintains compatibility with the SOT-583-8 package and supports the necessary 65 V rating and 1 A output current capability.
