- Built-in intelligence to ignite positive impedance CCFLs Universal panel interface Enhanced output drive capability Over 200 steps dimming control Low cost LCD TV inverter solution Constant operating frequency Operating frequency can be synchronized with external signal Integrated synchronized PWM dimming control with wide dimming range Built-in intelligence for ignition and normal operation of CCFLs Built-in open-lamp protection and overvoltage protection Optimized soft-start function Shutdown delay for input voltage brownout Supports multiple CCFLs the controller and LCD panel. OZ9932 drives all types of CCFLs and is able to ignite positive impedance CCFLs. OZ9932 provides a shutdown delay feature for input voltage brownout condition. The controller provides a wide dimming range by converting an external analog control input into a low-frequency Pulse Width Modulation (LPWM) dimming function. The control logic provides a regulated ignition voltage...
