Ideal for RGB and single-color applications such as indoor/outdoor LED video displays, decorative lighting, automotive interior lighting, and LCD backlighting, the MAX16824/MAX16825 three-channel high-brightness LED drivers are capable of delivering up to 150 mA to three separate strings of HB LEDs. These devices allow independent LED current adjustment of the three output channels by providing independent LED current sense for each channel.

To implement independent LED brightness adjustment, the MAX16824 provides three PWM dimming inputs, while the MAX16825 features a 4-wire serial interface that allows a microcontroller to control the PWM of the output channels. Housed in 16-pin TSSOPs, the parts also feature a 6.5 to 28-V input voltage and three 36-V-rated open-drain constant-current sink outputs. They provide an additional 5-V regulated output with 4-mA output current capability and thermal shutdown in the event of overheating.
