PMIC LED drivers refer to integrated circuits (ICs) designed to control LED illumination. LED (Light Emitting Diode) lighting systems in modern times typically require a control system to reduce power dissipation and optimize light output from the LEDs. PMIC LED drivers offer a broad range of features that make it an ideal solution for such systems, offering features such as on/off control, temperature protection, strobing, dimming, and current control. HVLED002TR is one such example of a PMIC LED driver, offering a range of features including PWM dimming, thermal protection, and a Comprehensive 3-Year Warranty.

HVLED002TR is a wide input voltage AC/DC LED driver, available with up to 80V input voltage and up to 150W output power, making it an ideal choice for applications ranging from high wattage and high temperature to low wattage, low temperature applications. It\'s specifically designed to enhance the stability and efficiency of LED systems, and provide advanced power-saving features. It\'s also highly flexible, with adjustable over-voltage protection, adjustable dimming and soft-start time, and low profile design.

The application field of HVLED002TR is extremely wide. It\'s commonly used in household lighting and outdoor applications such as street lighting, landscape lighting, and floodlighting, as well as for industrial applications such as commercial lighting, stage lighting, and studio lighting. HVLED002TR can also be used for lighting systems in the military, medical, automotive, and other specialized environments. It\'s also the perfect choice for indoor illuminations requiring advanced features, such as RGB and RGBW systems, as well as dimming and motion sensing capabilities.

The working principle of HVLED002TR is based on a highly efficient, buck-boost converter approach. The buck-boost converter is a type of switch-mode DC-DC converter which is particularly useful for LED lighting applications, as it is capable of operating regardless of the input voltage polarity, which is essential for LED systems, since the polarity of the currents changes over time.

The buck-boost converter in HVLED002TR consists of a power converter chip, a control IC, and a power FET. The power converter chip accepts an input voltage, and then sends a signal to the control IC, which in turn sends a signal to the power FET, which turns on and off in order to regulate the voltage and current within the system. The converter chip, control IC, and power FET are all interconnected, enabling the buck-boost converter to automatically adjust the output voltage.

In addition to voltage and current regulation, HVLED002TR also provides thermal protection, overload protection, and over-voltage protection. The thermal protection feature detects if the temperature reaches an unsafe level, and if so, it immediately stops the LED from operating to help prevent damage to the system. The overload protection feature prevents damage from occurring due to excessive current, and the over-voltage protection feature protects the LED driver from potential voltage spikes.

In conclusion, HVLED002TR is a wide input voltage AC/DC LED driver, capable of providing a range of features designed to enhance the stability and efficiency of LED-based lighting systems. With an extremely wide application field, it can be used for a variety of different applications, including household lighting, outdoor lighting, and industrial lighting systems. The working principle of HVLED002TR is based on a buck-boost converter, which is highly efficient and capable of automatically regulating the output voltage and current. It also provides thermal protection, overload protection, and over-voltage protection, making it an ideal choice for LED lighting systems.
