Introduction

AI Translation

The LTC1697 is designed to control a single 1W cold cathode fluorescent lamp (CCFL). An internal PWM dimming system maximizes efficiency and dimming range. Accurate lamp currents can be set with a single external resistor. The LTC1697 includes a synchronous current mode PWM controller with internal 1A MOSFET switches. It contains a 300kHz oscillator, 0.8V reference, and internal current sense. It operates from a 2.8V to 5.5 V input voltage. The LTC1697 also has a thermal limit and a shutdown that reduces supply current to <2μA. The LTC1697 is available in the MSOP - 10 package.
