NCP5005GEVB LED drivers are evaluation boards specifically designed to assist engineers in evaluating, designing and debugging LED drivers based on ON Semiconductor\'s advanced NCP5005G Buck LED drivers. It is a buck regulator configured to convert a 5 V input to a 0.9 V to 4.5 V regulated output, allowing an output current up to 250 mA. The device itself is based on NCP5005G switching regulator architecture and can be configured to operate in a wide range of applications.

The NCP5005GEVB is used in some of the most popular application fields such as automotive, industrial and consumer lighting. For automotive applications, the board is used as a complete solution for dimming and monitoring of headlights, signal lights and dashboard lights. In industrial applications, it is used as an effective energy saving device for lighting such as spotlights, high bays and warehouse lighting. Finally, in consumer applications, the board is used for products such as bulbs, task lights, wall packs and down lights.

The board is designed to meet automotive requirements, and has built-in protection features such as steady-state over-voltage (OVP) and under-voltage (UVP) protection, which helps to ensure reliable and safe operation of automotive lighting systems. The NCP5005G can be configured to operate from an input voltage range from 5V to 46V, making it versatile for a wide range of automotive applications. Additionally, the board also has a low-side current monitoring feature that helps to protect against short-circuited loads.

The working principle of NCP5005GEVB is a Buck Class-D switching regulator. The output voltage is reduced to a fraction of the input voltage through a series of pulses created by a dedicated on-chip oscillator. The current control loop then monitors the LED current to keep the LED current constant and equal to the desired level. The NCP5005GEVB also includes a frequency synchronization circuit, allowing the device to operate at higher frequencies than other buck LED drivers.

The board is designed to evaluate and optimize the performance of ON Semiconductor’s NCP5005G Buck LED Drivers when used in automotive, industrial and consumer applications. The NCP5005GEVB is a complete and versatile evaluation board that is packaged in a convenient form factor to enable easy integration in any design. It provides engineers with essential and valuable feedback about the performance of NCP5005G LED drivers, helping them to make informed decisions about the use of the device.
