MAX16807 Overview
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.
MAX16807 Key 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 with External Biasing Devices
- Open LED Detection (MAX16808)
