The HV9861ANG-G is a part of a wide range of LED drivers from PMIC – LED Drivers. It is capable of delivering regulated levels of power while also providing special features that enable it to adjust to different applications and driving conditions.

This LED driver works with input voltages ranging from 2.7V to 18V, with an adjustable output voltage of up to 2.6V and an adjustable output current of up to 400mA. It also has built-in safety features for protection against over voltage, over temperature and over current protection. The operating temperature of this driver is from 0℃ to +85 ℃.

The HV9861ANG-G is commonly used in a variety of applications such as illuminating parking lots, billboards and street lighting, as well as automotive lighting. It can also be used in backlight lighting for mobile phones, notePads and digital TVs.

The device provides a constant-current control that guarantees a stable light output over the specified input voltage range and temperature. This is achieved by first sensing the voltage across the LED terminals, and then adjusting the current flow to the LED to ensure that the light output is kept constant. In addition, the device also has special features that enable it to adjust the current output automatically to match the application’s requirements such as dimming range and brightness.

The device also features an external dimming control, an adjustable phase dimming control, and a PWM dimming control. The phase dimming control adjusts the power output of the device by monitoring an external phase signal and then controlling the current output of the chip accordingly. This ensures that the light output remains constant although the input voltage may be varied. The PWM dimming control adjusts the output current of the device according to the pulse width modulation input signals and thus adjusting the brightness.

In summary, the HV9861ANG-G LED driver from PMIC – LED Drivers combines a wide input voltage range, adjustable output voltage and current, as well as various safety features that provide reliable operation and allows for versatile applications. The device is ideal for outdoor lighting applications requiring dimming control and brightness adjustment.
