TPS923652DYYR

Overview

The TPS923652DYYR is a non-synchronous boost or buck-boost LED driver IC from Texas Instruments. It operates within an input voltage range of 4.5 V to 65 V and supports a maximum output current of 2 A. The device features a programmable switching frequency between 100 kHz and 2.2 MHz, with a maximum output voltage of 63 V. Packaged in a VSON-14 format, it functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-side N-channel power switch for efficient boost and buck-boost topologies
• Supports flexible dimming methods including analog, PWM, and hybrid control
• Includes comprehensive protection mechanisms such as thermal shutdown and cycle-by-cycle over-current protection

Applications

• General indoor and outdoor lighting systems
• LCD backlighting applications
• Automotive exterior lighting modules

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the ordering suffix matches the required reel quantity and tape-and-reel specifications. Cross-reference the component lot traceability with official TI documentation prior to final procurement decisions.

Selection Notes

Select this component for designs requiring a single-inductor solution capable of handling wide input voltage variations. The integrated switch reduces external component count compared to discrete solutions. Ensure the thermal management strategy accommodates the VSON-14 package limitations under maximum load conditions.

Part Context

This part belongs to the TPS92365x family of LED drivers designed for high-efficiency lighting applications. It complements other variants like the TPS923650 and TPS923654 by offering a mid-range current capability suitable for medium-power LED strings.

Replacement Considerations

Direct substitutes include TPS923650DYYR and TPS923654DYYR within the same family. Verify pin compatibility and current ratings when swapping between these variants.
