Description
OZ9902 is a dual, high power LED driver designed to build LED backlight for largesize LCD TV applications. It integrates two independently-controlled LED drivers to achieve optimum effi ciency. The drive outputs are phase-shifted by 180 degrees to minimize current ripple in high power applications.
0Z9902 supports independent Pulse Width Modulation (PWM) dimming control for each channel and common analog dimming control for both channels. It provides system design fl exibility for LCD TV with local dimming or 3D display mode.
