1 / 8 page  LTC1697 1 1697f ■ PDAs ■ Handheld Computers ■ Portable Instruments ■ Handheld GPS with Map Display ■ Handheld TV/Video Monitor ■ Operates from Single Li-Ion Battery ■ 2.8V to 5.5V Input Voltage Range ■ Very Low Shutdown Current: <2µA ■ Synchronous Buck Architecture for High Efficiency ■ PWM Dimming Frequency Adjustable with a Single Capacitor ■ Accurate Lamp Current Maximizes Lamp Lifetime ■ Fixed Frequency Operation at 300kHz ■ Internal or External PWM Dimming ■ Small 10-Pin MSOP Package The LTC ®1697 is designed to control a single 1W cold cathode fluorescent lamp (CCFL). An internal PWM dim- ming 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 5.5V 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.
