MAX16807 - Integrated 8-Channel LED Drivers

Description

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.

Features

  • Eight Constant-Current Output Channels (Up to 55mA Each).
  • ±3% Current Matching Among Outputs.
  • Paralleling Channels Allows Higher Current per LED String.
  • Outputs Rated for 36V Continuous Voltage.
  • Output-Enable Pin for PWM Dimming (Up to 30kHz).
  • One Resistor Sets LED Current for All Channels.
  • Wide Dimming Ratio Up to 5000:1.
  • Low Current-Sense Reference (300mV) for High Efficiency.
  • 8V to 26.5V Input Voltage or Higher.

www.DataSheet4U.com 19-0655; Rev 0; 10/06 Integrated 8-Channel LED Drivers with Switch-Mode Boost and SEPIC Controller General Description 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.
