LT1786FCS#TR Description
LT1786FCS#TR developed by Analog Devices is a type of SMBus programmable CCFL switching regulator providing the control function for Cold Cathode Fluorescent Lighting (CCFL). An efficient high current switch, an oscillator, output drive logic, control circuitry and a micropower 6-bit 100μA fullscale current output DAC are integrated in a 16-pin narrow SO package. High reliability and simple loop frequency compensation can be ensured based on current mode-switching techniques with cycle-by-cycle limiting.
