MAX16816 - Programmable Switch-Mode LED Driver

Description

The MAX16816 is a current-mode, high-brightness LED (HB LED) driver designed to control two external n-channel MOSFETs for single-string LED current regulation.

Features

  • through on-chip nonvolatile EEPROM registers. Adjustable features include a programmable soft-start, LED current (binning), external MOSFET gate driver supply voltage, slope compensation, leading-edge blanking time, and disabling/enabling of the RT oscillator. The MAX16816 is available in a 32-pin TQFN package with exposed pad and operates over the -40°C to +125°C automotive temperature range. Features o EEPROM-Programmable LED Current Binning o Wide Input Range: 5.9V to 76V with Cold Start Ope.

19-1054; Rev 0; 1/08 KIT ATION EVALU E L B AVAILA www.DataSheet4U.com Programmable Switch-Mode LED Driver with Analog-Controlled PWM Dimming General Description The MAX16816 is a current-mode, high-brightness LED (HB LED) driver designed to control two external n-channel MOSFETs for single-string LED current regulation. The MAX16816 integrates all the building blocks necessary to implement fixed-frequency HB LED drivers with wide-range dimming control and EEPROMprogrammable LED current binning with a factor of up to 1.6. This device is configurable to operate as a stepdown (buck), step-up (boost), or step-up/step-down (buck-boost) current regulator. Current-mode control with adjustable leading-edge blanking simplifies control-loop design.
