Integrated 8-Channel LED Driver with Switch-Mode Boost and SEPIC Controller
High-Efficiency, 8-Channel, Constant-Current, Linear LED Drivers with a Switch-Mode Controller and ±3% Current Matching Among Strings that Enables Paralleling of Output Currents Higher than 55mA per LED String
The MAX16807 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 MAX16807 current-mode PWM controller regulates the necessary voltage to the LED array. Depending on the input voltage and LED voltage range, it can be used with boost or buck-boost (SEPIC) topologies. The MAX16807 features an 8V to 26.5V input voltage range. A wide range of adjustable frequency (20kHz to 1MHz) allows design optimization for efficiency and minimum board space.
The MAX16807 LED driver includes eight open-drain, constant-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 dimming 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 MAX16807 operates either in stand-alone mode or with a microcontroller (µC) using an industry-standard, 4-wire serial interface.
The MAX16807 includes overtemperature protection, operates over the full -40°C to +125°C temperature range, and is available in a thermally enhanced, 28-pin TSSOP exposed paddle package.
