Product Overview

The LT1768CGN#PBF is a high power CCFL Controller for wide dimming range and maximum lamp lifetime. The LT® 1768 is designed to control single or multiple cold cathode fluorescent lamp (CCFL) displays. Unique multimode dimming scheme combines both linear and PWM control functions to maximize lamp life, efficiency and dimming range. Accurate maximum and minimum lamp currents can be easily set. The LT1768 can detect and protect against lamp failures and over-voltage start-up conditions. It is designed to provide maximum flexibility with a minimum number of external components. The LT1768 is a current mode PWM controller with a 1.5A MOSFET driver for high power applications. It contains a 350kHz oscillator, 5V reference and a current sense comparator with a 100mV threshold. It operates from an 8 to 24V input voltage. The LT1768 also has under-voltage lockout, thermal limit and a shutdown pin that reduces supply current to 65µA.
  • Ultrawide Multimode Dimming™ Range
  • Multiple lamp capability
  • Programmable PWM dimming range and frequency
  • No lamp flicker under all supply and load conditions
  • Open lamp detection and protection
  • 100mV Current sense threshold
