The LT1182/LT1183/LT1184F/LT1184 family of dual fixed frequency, current mode switching regulators that provide the control function for cold cathode fluorescent lighting and liquid-crystal display contrast, are described.
cold cathode fluorescent lighting
LCD display contrast
Current generation portable computers and instruments use backlit liquid-crystal displays (LCDs). Cold cathode fluorescent lamps (CCFLs) provide the highest available efficiency for backlighting the display. The lamp requires high voltage AC to operate, mandating an efficient, high voltage DC/AC converter. The LCD also requires ...
