MAX17061 - 8-String White LED Driver

Datasheet Summary

Description

The MAX17061 is a high-efficiency driver for white lightemitting diodes (LEDs).

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

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 MAX17061 also features short LED detection. The shorted strings are also disabled after a 2ms fault blanking interval. The controller features cycle-bycycle current limit to provide stable operation and softstart capability. If the MAX17061 is in current-.

19-3211; Rev 0; 1/08 www.DataSheet4U.com 8-String White LED Driver with SMBus for LCD Panel Applications General Description The MAX17061 is a high-efficiency driver for white lightemitting diodes (LEDs). 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 eight strings in parallel and 10 LEDs per string. Each string is terminated with ballast that achieves ±1.5% current-regulation accuracy between strings, ensuring even LED brightness. The MAX17061 has a wide inputvoltage range from 4.5V to 26V, and provides a fixed 25mA or adjustable 15mA to 30mA full-scale LED current.
