RGB LED driver delivers up to 80 mA per output

By providing 24 constant-current outputs capable of driving RGB LEDs at up to 80mA, the STP24DP05 LED driver performs the work of three conventional 8-output drivers within a compact TQFP48, 7 x 7-mm footprint. The driver is a serial-in, parallel-out FIFO supporting operation at 25 MHz for high serial data rates enabling responsive image rendition.

The driving current is adjusted using one external resistor per color group of eight outputs, allowing the maximum brightness of red, green and blue channels to be optimized independently. Compatibility with 3.3- and 5-V data levels promotes interoperability with a wide variety of host controllers, such as the 8-bit ST7FLITE MCU. Operating temperature is –40° to 125°C.
