<p>The HV9961NG-G is a constant current integrated circuit designed for driving high-power white LEDs. The device can be operated with a wide range of input voltages, allowing for compatibility with a wide range of systems. It is ideal for many different applications, from automotive and medical equipment to industrial displays. The HV9961NG-G offers outstanding efficiency of more than 91% and is capable of providing constant current to drive up to 10 white LEDs in parallel.</p><p>The HV9961NG-G features an on-chip error amplifier that is used for controlling the LED current. The on-chip error amplifier has a feedback loop that is connected to the LED string, allowing it to detect the LED current and adjust the LED current accordingly. In addition, the device also has an adjustable current setting pin that allows the user to adjust the LED current to meet their needs.</p><p>The HV9961NG-G also features a built-in start-up delay circuit. This circuit is designed to prevent damage to the LEDs due to inrush current at initial start-up. The start-up delay circuit delays the initial LED current by up to 2 seconds. This allows the device to be used in applications where sudden power-on can cause damage to the LEDs.</p><p>The HV9961NG-G is also designed with a thermally efficient package. The package is designed to help transfer excess heat away from the device, helping to maintain cooler temperatures. This helps to extend the life of the device and keep the LED current at a constant level.</p><p>The HV9961NG-G is an ideal solution for many industrial, automotive, and medical applications, where constant current conditions are essential. The device is capable of driving a high number of LEDs with a maximum output current of 2A. With its excellent efficiency and wide input range, it is a great choice for many different applications.</p>
