Machine Translated by Google Features DP5020 CMOS 16BIT LED DRIVER CIRCUIT DP5020 is a driver IC designed for LED display panels. It has a built-in CMOS shift register and latch function, which can convert the serial input The DP5020 has 16 current sources that can provide a constant current of 2~60mA at each output port. The flow rate is used to drive the LED. Each OUT driving channel output can be short-circuited to obtain a larger current output. When the environment changes, the output The output current is affected very little. At the same time, external resistors with different resistance values (REXT) can be used to adjust the current size of each output port of DP5020. Therefore, the brightness of the LED can be precisely controlled, which is suitable for high-quality white balance display drive modules. This product has excellent performance and reliable quality.
