MAX17105 Datasheet 8-string Wled Driver

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4562; Rev 1; 12/09 TION KIT EVALUA BLE AVAILA 8-String WLED Driver with Integrated Step-Up Regulator and SMBus/PWM Dimming.

General Description

The MAX17105 is a high-efficiency driver for white-lightemitting diodes (WLEDs).

It is designed for large liquidcrystal displays (LCDs) that employ an array of LEDs as the light source.

An internal switch-current mode step-up controller drives the LED array, which can be configured for up to 8 strings in parallel and 10 LEDs per string.

Key Features

  • to protect the controller from fault conditions. Separate feedback loops limit the output voltage under any circumstance, ensuring safe operation. Once an open string is detected, the string is disabled while other strings operate normally. The MAX17105 also features short LED detection. The shorted strings are also disabled. The controller features cycle-by-cycle current limit to provide constant operation and soft-start capability. If the MAX17105 is in currentlimit condition, the step-up regu.
