TPS92401MRRVR

LED Driver IC Overview

The TPS92401MRRVR is a four-channel LED lighting driver IC from Texas Instruments, designed for high-power applications. It features a floating switch topology capable of delivering up to 5 A output current per channel. The device operates within a supply voltage range of 4.6 V to 65 V and supports an output voltage up to 63 V. It functions at a switching frequency of 60 kHz and is housed in a VQFN-36 package. The component is rated for operation between -40°C and +85°C.

LED Driver IC Feature Summary

• Integrates four independent high-side channels for driving multiple LED strings simultaneously.
• Supports flexible floating switch topology suitable for various LED configurations.
• Includes integrated protection mechanisms to ensure reliable operation under fault conditions.

LED Driver IC Applications

• General illumination systems requiring multi-channel LED control
• Industrial lighting fixtures with high power density requirements
• Commercial building lighting infrastructure

LED Driver IC Procurement Notes

Verify the specific suffix MRRVR against the manufacturer datasheet to confirm the reel packaging configuration and tape dimensions. Ensure the ordering part number matches the exact temperature grade and package variant required for your design. Cross-reference the RoHS compliance status directly with the official documentation before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when designing circuits that require four independent LED channels driven by a single controller. The 5 A current capability suits high-brightness applications. Verify that the input voltage range aligns with the system power supply and that the thermal performance of the VQFN-36 package meets the heat dissipation needs of the target enclosure.

LED Driver IC Part Context

This device belongs to the TPS92401 series of LED drivers. It is distinct from automotive-grade variants like the TPS929240AQDCPRQ1, which offers 24 channels but lower individual current. It differs from general-purpose regulators such as the TPS62401DRCT, focusing specifically on LED string management rather than generic DC-DC conversion.

LED Driver IC Replacement Considerations

Direct substitutes are not explicitly confirmed in the provided data. Evaluate other members of the TPS92401 family or similar TI LED drivers based on channel count and current rating. Verify pin compatibility and electrical parameters before considering alternative part numbers.
