MAX16807, MAX16808 Integrated 8-Channel LED Drivers With Switch-Mode Boost And SEPIC Controller

The MAX16807 MAX16808 are integrated, high-efficiency white or RGB LED Drivers They are designed for LCD backlighting and other LED lighting applications with multiple strings of LEDs The MAX16807 MAX16808 's 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 MAX16808 feature 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 MAX16808 LED Drivers include eight open-drain, constant-current-sinking LED Driver outputs rated fo 589 r 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 MAX16808 operate either in stand-alone mode or with a Microcontroller (C) using an industry-standard, 4-wire serial Interface The MAX16808 includes circuitry that automatically detects open-circuit LEDs
The MAX16807 MAX16808 include overtemperature protection, operate over the full -40C to +125C temperature range, and are available in a thermally enhanced, 28-pin TSSOP exposed paddle package.
