THL3501-B is a high-efficiency LED driver integrated power supply with a range of adaptive control functions formulated specifically for the LED lighting applications. It is the ideal power contactor bringing together a high-efficiency voltage regulator, power MOSFET switch and accurate current-sensing function. It is categorized as a PMIC (Power Management Integrated Circuits) and LED driver due to its wide range of applications as well as its innovative characteristics.

The product is widely applied in the field of LED lighting. It contains power correction and feedback through which it actively controls the intensity, color or size of the LEDs for lighting coverage. THL3501-B works collaboratively with many smart lighting systems to guard the lighting performance and calibrate the state of LEDs. Furthermore, it has been designed with the demand to function in extreme temperatures between -20~85degree Celsius, making it suitable for exterior use.

The next generation of fabrication techniques employed with the THL3501-B enable the PCB to take on a more sophisticated design. It simplifies the wiring process and provides a high-efficiency heat dissipation system, leading to smaller and lighter LED lights. The product contains a few peripheral components, such as a thermistor for over-temperature protection, fuse to guard against inrush current as well as various capacitors, which allow better stability and fewer interferences.

The working principle of THL3501-B is achieved through various integrated components including the boost converter, power MOSFET, current sense and temperature sense. The product utilizes an adjustable DC-DC switching regulator to turn the pressure from the input source into constant current output for LEDs. The application of the power MOSFET enables a high level of efficiency, fast response, and low level of EMI (Electro-Magnetic Interference). The integrated current sense feature detects the current sourced to the LEDs and adjusts the current level to the optimal values while the micro-sensor monitors the junction temperature as well as the thermal environment.

The applicable components and innovative features of the THL3501-B make it an attractive choice for many LED configurations. Furthermore, it has been tailored to meet the highest standards in terms of constancy and quality of the LED lights. Its versatile performance and reliability make it the ideal partner for a wide range of LED applications.
