Introduction
TPS92518HVQPWPTQ1, produced by Texas Instruments, is a LED driver that belongs to the PMIC (Power Management Integrated Circuit) family. It is a monolithic current-mode LED driver with internal power FETs, capable of providing a highly-regulated constant-current output. With the impressive capabilities in terms of accuracy, efficiency, and power handling, the device is an ideal choice for driving multiple LED strings in applications such as industrial, consumer, or automotive lighting.Application Field
This device is specialized for driving LEDs, aimed towards a wide range of applications, such as industrial lighting, consumer products, and automotive lighting. With the impressive specifications and benefits that the TPS92518HVQPWPTQ1 offers, it is capable of providing a flexible solution to any LED driving needs.For industrial lighting applications, its high-efficiency, robust design, and smart features make it the ideal choice. Industrial lighting requires that the device be extremely reliable, with the ability to drive multiple LEDs. The TPS92518HVQPWPTQ1 is capable of providing precisely regulated current, while providing easy setup and control. Its design also allows for smooth dimming capabilities, while maintaining superior efficiency and accuracy. When it comes to consumer products, the device is ideal for lighting, with its low operating voltage and power consumption, along with its high accuracy and reliability. Its small size and low cost are also attractive to consumer products manufacturers, as the device does not add a lot of cost to the final product. Its built-in protection functions make it suitable for small-scale applications too, such as making sure all the LEDs remain within their specified parameters. The TPS92518HVQPWPTQ1 is also suitable for driving LED strings in automotive lighting applications. With its low off-state leakage current, low switching frequency and high efficiency, it is ideal for automotive lighting applications, as it does not require a lot of energy to switch the LED on and off. Furthermore, its overload protection features will ensure the safety of the automotive system.Working Principle
The TPS92518HVQPWPTQ1 is a monolithic current-mode LED driver, powered from a wide 3.2 V to 24 V power source. It can switch loads up to 100mA and the connected LEDs will be kept at the accurately regulated constant current. Resonant boost architecture is used for minimize power and increased efficiency.The device is controlled either through a PMOS transistor on its Enable pin or by an external sense resistor, depending on the application. With the PMOS option, once the voltage on the Enable pin is above 1.8V, the device turns on and the LEDs start emitting light. Once the voltage goes below 1.8V, the device turns off, thereby disabling the LEDs. With the sense resistor option, once the LED current exceeds the threshold value, the device shuts down and the LED current is reduced to the threshold level.The TPS92518HVQPWPTQ1 features protection features such as thermal shutdown and current limit protection, to prevent damage due to temperature, overload or accidental short circuits. Furthermore, it is also integrates a power supply reduced track (PSUV) mode. This mode reduces the supply voltage to a low nominal value as the LED current decreases, thereby saving power and increasing efficiency. This device also provides a low quiescent current, which results in a lower power loss.Conclusion
In summary, the TPS92518HVQPWPTQ1 is a high-efficiency, low-cost single channel LED driver that is perfect for applications such as industrial lighting, consumer products, and automotive lighting. It is capable of delivering accurately regulated current, while providing excellent thermal and short-circuit protection. Its resonant boost architecture ensures high efficiency, while its power save mode ensures minimal power consumption.The specific data is subject to PDF, and the above content is for reference
