Evaluation Boards - LED Drivers

The LM3404EVAL/NOPB evaluation board is a great example of the power of LED drivers used in many applications.

The LM3404EVAL/NOPB is an LED driver designed to evaluate the performance and features of the LM3404 current-controlled step-down LED driver with integrated HV switch. It is a compact, high-efficiency LED driver that allows for excellent dynamic control of LEDs for dimming and color mixing. The high-voltage (HV) switch prevents the circuit from damage due to an open load and provides steady output current under closed loop control.

The most common application for the LM3404EVAL/NOPB is in architectural lighting systems. These systems are used to create ambient lighting effects in buildings, and the LM3404EVAL/NOPB can be used to control the brightness and color of the LEDs used in the system. The HV switch allows the system to continue to provide power despite an open load, which is necessary in architectural lighting as the load can often change quickly due to the changing layouts of the environment.

In addition to its use in architectural lighting, the LM3404EVAL/NOPB can also be used in a variety of other applications. The power-conversion efficiency makes it ideal for a range of DC-DC conversion applications, and its wide input-voltage range allows it to be used in automotive and industrial applications as well. The HV switch also allows for protection against overloads in a variety of circumstances.

The LM3404EVAL/NOPB\'s working principle is based on the use of current control. The board contains a high-voltage switch connected in series, which provides current control of the output current. The output current is controlled using a voltage signal and a feedback circuit. The voltage signal is applied to the control terminal of the high-voltage switch and the feedback signal is analyzed in order to calculate the duty cycle of the switch. The duty cycle is then used to determine the amount of current flowing across the switch.

The output current can be adjusted by changing the voltage signal or by changing the feedback signal. The board also supports an adjustable-gain function which allows for finer control over the output current. The board also has an open circuit detector which will shut off the output current when no load is detected.

In summary, the LM3404EVAL/NOPB is a powerful LED driver evaluation board designed to provide excellent dynamic control of LED lighting applications. The use of current control, combined with the open circuit detector, allows for superior protection and control when used in a variety of applications. The LM3404EVAL/NOPB can be used in architectures, Automotive and industrial applications, offering excellent power-conversion efficiency and wide input-voltage ranges.
