Product Summary
The LT1186FCS#TR is a DAC programmable CCFL switching regulator. The IC includes an efficient high current switch, an oscillator, output drive logic, control circuitry and a micropower 8-bit 50µA fullscale current output DAC. The LT1186F control circuitry operates from a logic supply voltage of 3.3V or 5V. The IC also has a battery supply voltage pin that operates from 4.5V to 30V. The LT1186F draws 6mA typical quiescent current.
