Integrated circuits (ICs) that are used to supply power to LED lights are called LED Drivers. LED drivers are typically used when high power LED lights require a higher voltage and current than what can typically be supplied by a power source. The TB62785NG is a voltage regulator IC that is used for LED drivers applications. This article will discuss the TB62785NG\'s application field and working principle.

Application Field of the TB62785NG

The TB62785NG integrates the functions of voltage and current regulation, which provides a highly-versatile solution for various LED applications. The TB62785NG is suitable for use in street lamps, flood lamps, car head lamps, and other applications that require high brightness LEDs. It is also suitable for high current applications, such as backlights for radio panels, LCD panels, and light boxes. Furthermore, the TB62785NG is also suitable for applications that require a wide operating temperature range, such as outdoor lighting.

Working Principles of the TB62785NG

The TB62785NG is an IC that is designed for LED driver applications. The chip is made up of a voltage regulator, constant current regulator, fault detection and protection circuits. The voltage regulator is used to convert the input voltage to a regulated output voltage, which is necessary for providing a stable output to the LEDs. The constant current regulator regulates the current output to the LEDs, ensuring that they receive the proper current to reach their full brightness. The fault detection and protection circuit helps protect the LEDs against short circuits, over-voltage, and over-current situations.

The driver also includes a pulse width modulation (PWM) control circuit, which allows the user to adjust the brightness of the LEDs by changing the pulse width of the PWM signal. The TB62785NG also has a temperature detection circuit, which can detect the temperature of the LEDs and can automatically reduce the current output to the LEDs in case of overheating.

Conclusion

The TB62785NG is an LED driver IC that provides an efficient and stable power supply for LED lights. It integrates voltage and current regulation, fault detection and protection circuits, PWM control, and temperature detection, providing a highly-versatile solution for various LED applications.
