OZ9936GN LCD Monitor CCFL Inverter Controller FEATURES Built-in intelligence to ignite positive impedance CCFLs Low cost LCD monitor inverter solution Constant operating frequency Built-in intelligence for ignition and normal operation of CCFLs Built-in open-lamp protection and overvoltage protection Optimized soft-start function Supports both analog and external PWM dimming control Shutdown delay for input brownout condition Higher reliability and longer CCFL life Supports multiple CCFLs Minimum external components OZ9936GN operates at a constant operating frequency that eliminates any undesired interference between the controller and LCD panel. OZ9936GN drives all types of CCFLs and is able to ignite positive impedance CCFLs. OZ9936GN provides a shutdown delay feature for input brownout condition. The control logic provides a regulated ignition voltage and appropriate protection for overvoltage or over-current conditions. The OZ9936GN offers a high level of integr […]
