The LP8860HQVFPRQ1 is a High Brightness LED (HB LED) driver, a Peripheral Monitoring & Controlling Integrated Circuit (PMIC). It is widely used in new generation of HB LEDs due to its advanced and convenient features. In this article, we will explore the application field and working principles of this PMIC.

Applications of the LP8860HQVFPRQ1

The LP8860HQVFPRQ1 is designed to control the current for driving strings of LEDs for general lighting, such as for lighting in vehicles, homes, commercial buildings, industrial facilities and street lighting. The PMIC can drive up to 57x3 strings LEDs with its built-in current regulators. It can be used with variety of LEDs, including high-power white LEDs, RGB LEDs and warm/cool white LEDs. It can also be used for general illumination with different current levels to meet the requirements. The LP8860HQVFPRQ1 has wide range of operating temperatures, making it suitable for use in many different types of applications.

The LP8860HQVFPRQ1 can be used with different types of HB LEDs. It is capable of driving up to 120W of LEDs with high efficiency and low thermal losses. It also has over-voltage and over-temperature protection that makes it resistant to potential damage. It supports both LED Scanning mode and PWM dimming control mode. The LED Scanning mode can provide high frame rates, low flicker and overall excellent performance. The PWM dimming control allows for manual setting of current and dimming level, enabling the user to have more control over their lighting setup.

Working Principle of LP8860HQVFPRQ1

The LP8860HQVFPRQ1 is a programmable high current driver, which uses Pulse Width Modulation (PWM) dimming control to regulate the current for the external LEDs. The current for the LEDs is adjusted by setting the duty cycle of the PWM signal. The LP8860HQVFPRQ1 can also be used in conjunction with an external resistor to set the current of the LEDs, allowing the user to adjust the current level to their desired power level.

The LP8860HQVFPRQ1 contains multiple current drivers and a digital control logic. The current drivers act as switches which can turn on and off the current to the LEDs. The digital control logic acts as a processor which manipulates the current driver signals in order to control the output current. It is capable of providing very precise current control while being very efficient. The LP8860HQVFPRQ1 can also be used to control brightness or color of the LEDs through dimming control. The current level of the LEDs can be adjusted from 0-250mA, depending on the type of LEDs used.

Conclusion

The LP8860HQVFPRQ1 PMIC can be used for a variety of applications, from general illumination to driving HB LEDs. It offers high efficiency, low thermal losses and excellent performance. The PWM dimming control offers manual setting of current and dimming level, giving the user greater control over their lighting setup. With its wide temperature range and over-voltage and over-temperature protection, the LP8860HQVFPRQ1 is a reliable and cost-effective choice for any LED-based system.
