LT1186F DAC Programmable CCFL Switching Regulator (Bits-to-NitsTM) FEATURES s s s s s s APPLICATIONS s s s face modes including standard SPI mode and pulse mode. On power-up, the DAC counter resets to half-scale and the Wide Battery Input Range: 4.5V to 30V DAC configures to SPI or pulse mode depending on the CS Grounded Lamp or Floating Lamp Configurations signal level. In SPI mode, the system microprocessor Open Lamp Protection serially transfers the present 8-bit data and reads back the Precision 50µA Full-Scale DAC Programming Current previous 8-bit data.
