The LP5523EVM/NOPB is an evaluation board specifically designed for Texas Instruments’ LP5523 Constant Current LED Driver. The evaluation board demonstrates the features of the LP5523 and can evaluate the performance of the product with a TCM32IOB as the master module. The LP5523 is excellent for driving both constant current and switching between LEDs in automotive, consumer and industrial applications ranging from lighting, to medical, and industrial control.

Application field

The LP5523EVM/NOPB board is designed to facilitate the user evaluation of the various features of the LP5523 for automotive and consumer applications. It is particularly suitable for applications that require precise controlled current loads, such as LED matrix, automotive interior and exterior lighting applications, smart lighting for home networks, and medical and industrial control, among others.

Working Principle

The LP5523EVM/NOPB consists of a master module connected to the LP5523 Eval-board, which is powered by a 12 V supply. The TCM32IOB module acts as a “master” module to provide application control signals to the LP5523 Eval board. The board features 10 constant current sink channels, divided into three groups of three channels. Each group is independently controllable so that it can be used to control up to 3 distinct LEDs independently. The current sink can be adjusted using the programmable current adjustment feature.The board also features an LED indicator LED, which indicates the power supply status, and LEDs for the 10 channels, so that the user can easily see the switching status of each channel. In addition, the board can be connected to the external application via the two I/Os operated through the TCM32IOB. The integrated PWM (pulse width modulation) control of the LP5523 also allows for smooth and efficient dimming of LEDs along with energy savings.

Conclusion

In conclusion, the LP5523EVM/NOPB evaluation board is designed to facilitate user evaluation of the LP5523 for a range of consumer and automotive applications including lighting, medical and industrial control. The board features 10 constant current sink channels and an LED indicator LED, so that the user can easily see the switching status of each channel. In addition, the board can be connected to the external application via the two I/Os operated through the TCM32IOB master module. The use of the LP5523EVM/NOPB evaluation board should allow designers to easily evaluate the features and performance of the LP5523 LED driver for their specific applications.
