Evaluation Boards - LED Drivers

DM330014 is an evaluation board designed to demonstrate the capabilities of a variety of LED drivers. It is capable of supporting various types of LED backlights, such as White-Light LEDs (WLEDs), RGB LEDs, ELV and AEL LEDs, matrix LEDs, as well as bulk LEDs. It also supports a wide range of dimming functions.

Application Field

DM330014 is applicable in several backlighting and lighting applications. It is used in flat panel displays, projection and large format displays, smart lighting, automotive displays and instrument clusters, as well as general lighting. Its small size also makes it easy to use in compact lighting designs. Some of the other applications include digital signage displays, keyboards, and gaming displays.

Working Principle

DM330014 consists of an evaluation board, DC power supply and a control software. The evaluation board provides a platform for the user to evaluate the performance characteristics of the LED drivers. The DC power supply is used to supply power to the LED drivers. The control software helps in configuring and monitoring the LED driver’s parameters such as brightness, current and voltage.The evaluation board consists of several components, such as an LED driver, a light-sensing diode, an LED connector and a control interface. The LED driver is used to increase current and voltage levels to the LED, while controlling the brightness of the LED. The light-sensing diode is used to detect the level of light and control the LED driver accordingly. The LED connector is used to connect the LED to the driver. The control interface is used to configure and monitor the LED driver’s parameters.DM330014 is also equipped with a wide range of dimming functions, such as pulse-width modulation (PWM), analog voltage control, and 1kHz digital control. The PWM dimming mode can be used to set the brightness of LEDs. The analog voltage control mode is used to adjust the voltage to the LEDs and hence their brightness. The 1kHz digital control mode can be used to control the brightnes of multiple channels all at once.

Conclusion

DM330014 is a versatile and comprehensive LED driver evaluation board that supports a wide range of LED backlights and allows a user to evaluate the performance characteristics of the LED drivers. It features an evaluation board, a DC power supply and control software, and is equipped with several dimming functions such as PWM, analog voltage control, and 1kHz digital control. The board is mainly used in flat panel displays, projection and large format displays, smart lighting, and instrument clusters, as well as general lighting.
