Linear Technology LT1186F CCFL Switching Regulator Datasheet
The LT1186F is a fixed frequency, current mode, switching regulator that provides control functions for Cold Cathode Fluorescent Lighting (CCFL). The IC includes an efficient high current switch, an oscillator, output drive logic, and a micropower 8-bit full-scale current output DAC. This device allows for simple 'bits-to-lamp current control' via Standard SPI Mode or Pulse Mode interfaces.
The regulator operates from a logic supply voltage of 3.3V or 5V and features a battery supply voltage pin operating from 4.5V to 30V. It utilizes a 200kHz switching frequency to minimize magnetic component size and includes open lamp protection, grounded or floating lamp configurations, and active low shutdown functionality.
