Dual Channel DC/DC converter• Constant current or voltage output• Drives one string of high power LEDs per channel• 180 degrees phase-shift between the two driver outputs• Independent PWM dimming control for each channel• Analog dimming• Constant operation frequency; and Operation frequency synchronization• Power MOSFET over-current protection• Over-voltage protection• Output to return and Output to ground short-circuit protection• Output over load protection• Limited Current Condition (LCC) protection• Thermal protection• LED fault status outputGENERAL DESCRIPTIONOZ9902 is a dual, high power LED driver designed to build LED backlight for large-size LCD TV applications. It integrates two independently-controlled LED drivers to achieve optimum efficiency. The drive outputs are phase-shifted by 180 degrees to minimize current ripple in high power applications.OZ9902 supports independent Pulse Width Modulation (PWM) dimming control for each channel and common analog dimming control for both channels. It provides system design flexibility for LCD TV with local dimming or 3D
