1 / 20 page General Description The MAX16809 is an integrated, high-efficiency white or RGB LED driver. It is designed for LCD backlighting and other LED lighting applications with multiple strings of LEDs. The MAX16809’s current-mode PWM con- troller regulates the necessary voltage to the LED array. Depending on the input voltage and LED voltage range, this device can be used with boost or buck- boost (SEPIC) topologies. The MAX16809 LED driver includes 16 open-drain, con- stant-current-sinking LED driver outputs rated for 36V continuous operation. The LED current-control circuitry achieves ±3% current matching among strings and enables paralleling of outputs for LED string currents higher than 55mA. The output-enable pin is used for simultaneous PWM dimming of all output channels. Dimming frequency range is 50Hz to 30kHz and dim- ming ratio is up to 5000:1. The constant-current outputs are single resistor programmable and the LED current can be adjusted up to 55mA per output channel. The MAX16809 operates either in stand-alone mode or with a microcontroller (μC) using an industry-standard, 4- wire serial interface. The MAX16809 includes overtemperature protection, operates over the full -40°C to +125°C temperature range, and is available in a 5mm x 7mm thermally enhanced, 38-pin TQFN exposed paddle package.
