LT1186F Datasheet (Linear Technology) - DAC Programmable CCFL Switching Regulator(Bits-to-NitsTM)

LT1186F, DAC Programmable CCFL Switching Regulator(Bits-to-NitsTM)

The LT ®1186F is a fixed frequency, current mode, switching regulator that provides the control function for Cold Cathode Fluorescent Lighting (CCFL).

The IC includes an efficient high current switch, an oscillator, output drive logic, control circuitry and a micropower 8-bit 50µA fullscale current

LT1186F 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.
