LED Drivers and LPV-35-12 application field and working principle

An LED driver is an electrical device used to power a light-emitting diode (LED). It is an important component that regulates the current being delivered to the LED to ensure the LED operates within its safe operating limits, providing the maximum lifespan and highest possible efficiency.

The LPV-35-12 is a fully integrated step-down converter type LED driver that provides all the functions necessary to power a single color line voltage LED like those used in light bulbs, low voltage direct current (DC) LED strips, LED signs and strings of decorative LED lights.

Application Field

The LPV-35-12 is an ideal LED driver for high power single color LED applications which include: street lighting, architectural and decorative lighting, outdoor lighting, signal and indication applications, residential LED lighting, and many others.

Working Principle

The LPV-35-12 LED driver uses an integrated advanced buck converter to power the LEDs. The integrated buck converter works by taking in a high input voltage, converting it to a low output voltage, and then regulating it to maintain a constant current which keeps the LED brightness consistent over time. The LPV-35-12 also features a wide ultrasonic frequency range of 20kHz~300kHz with adjustable soft start and soft dimming capabilities. This driver also features a wide input voltage range of 9~35V DC and is capable of delivering up to 12A of output current.

The adjustable boost converter found in the LPV-35-12 uses a proprietary low no-load power consumption control algorithm which enables it to operate at a high efficiency of up to 95%. The driver is also protected against overcurrent, overvoltage and thermal conditions.

Conclusion

The LPV-35-12 LED Driver is an efficient, cost-effective and reliable solution for powering single color LEDs. Its wide voltage range, adjustable soft start and soft dimming capabilities, and high efficiency make the driver very suitable for a wide range of LED applications. The driver is also protected against overcurrent, overvoltage and thermal conditions to ensure the safety and long lifespan of the LED.
