19-0658; Rev 0; 11/06 KIT ATION EVALU E L B A AVAIL Six-String White LED Driver with Active Current Balancing for LCD Panel Applications General Description The MAX8790 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. A current-mode step-up controller drives up to six parallel strings of multiple series-connected LEDs. Each string is terminated with ballast that achieves ±1.5% current regulation accuracy, ensuring even brightness for all LEDs. The MAX8790 has a wide input-voltage range from 4.5V to 26V, and provides a fixed 20mA or adjustable 15mA to 25mA full-scale...
