TLD1020-12 is a module of LED driver in the market, specially designed for industrial lighting and commercial luminaires. The TLD1020-12 includes a high-efficiency LED driver IC that can enable designers to meet requirements such as efficiency, product size, weight and cost.

The TLD1020-12 is an isolated LED driver that delivers 90-265V ac input to deliver an output of 12Vdc with greater than 90% efficiency. The power conversion is achieved through a current feedback loop that automatically detects and maintains the LED string current. The TLD1020-12 module has two outputs that can drive two LED strings in parallel or series to 12Vdc.

The TLD1020-12 driver is fully programmable allowing output current set-ability from 500mA-1400mA, using the external potentiometer. Protection against short circuits, overtemperature, overcurrent and open circuits is built-in to ensure user safety and reliable operation. The driver also features a soft start function to eliminate inrush current.

The application field of the TLD1020-12 module involves LED lighting control, industrial control lighting, outdoor lighting, and automotive lighting systems. The module is also widely used in commercial illumination, such as retail lighting, monument lighting, entertainment lighting, and art installations. The module is suitable for all types of high-power LED applications, such as street lighting, highway lighting, urban lighting, and tunnel lighting.

For its working principle, the TLD1020-12 module uses closed loop control technology for the output current, thus eliminating the traditional pulse width modulation (PWM) technique. When the power is applied, the LED driver IC will start the power conversion by controlling the current feedback loop, resulting in a precise and stable output voltage. The output current is adjustable through an external potentiometer. The output voltage of the module will remain fixed, despite changes in input voltage or LED string temperature.

The main components of the module include a high-efficiency LED driver IC, a soft-start resistor, a thermal shutdown resistor, a power-on indicator, an open-circuit protection diode, a schottky diode, an external voltage-adjusting potentiometer, a power MOSFET, and two output terminals. All the components are of top quality and are certified for safe and reliable operation.

In conclusion, the TLD1020-12 module is a high-performance LED driver module, ideal for a wide range of LED lighting applications. It is capable of delivering up to 90-265Vac input to 12Vdc with up to 90% efficiency. The driver features programmable output current set-ability, external voltage-adjusting potentiometer, short-circuit, overtemperature, open-circuit, and overcurrent protection, as well as a power-on indicator. The module is ideal for LED lighting control, industrial control lighting, outdoor lighting, automotive lighting systems, commercial illumination, and other high-power LED applications.
