WWW.Microsemi .COM LLXX11669911BB LX1691B Enhanced Multi-Mode CCFL Controller TM PRODUCTION DATA SHEET KEY FEATURES DESCRIPTION The LX1691B is an enhanced Direct control lamp current amplitude and duty Wide Input Voltage Capable Drive CCFL (Cold Cathode Fluorescent cycle simultaneously or separately. Simultaneous Amplitude And Lamp) Controller. Its architecture is based on Designers can select normal or reverse Duty Cycle Dimming Modes the LX1691. The LX1691B is optimized for polarity dimming and precisely program Resistor Programmable min wide input voltage applications. It is similar minimum and maximum lamp currents with and max Lamp Currents to the LX1691 except it has a guaranteed resistors. Fault protection includes open Digital Dimming Can Synch To 1 minimum lamp strike interval of one second lamp voltage regulation and shutdown for External Or Internal Clocks to meet notebook and monitor panel over voltage and over current conditions. 120 ms Power On Delay manufacturers specifications. The B The LX1691B employs Microsemis proven Open Or Shorted Lamp version also adds feed forward input voltage and patented strike method that allows Regulation & Shutdown sensing to enhance transient response when significant efficiency gains while On Chip Full Wave Lamp used in inverters that derive lamp power guaranteeing strong striking power at all Current Rectifier from unregulated input supplies and operating temperatures. Our method 16 Pin TSSOP Package batteries. sweeps strike frequency smoothly up to the Very Stable Oscillator with On- The LX1691B can also be used with unloaded resonant frequency of the lamp Chip Timing Capacitor fixed input supplies where it produces and high voltage transformer. This, coupled Enhanced Digital Dimming performance equal to the LX1691. with the LX1691Bs active high output Resolution LX1691B based inverter modules can be voltage regulation, produces just enough designed for virtually any CCFL appliance strike voltage without generating BENEFITS from digital cameras and PDAs to big unpredictable high voltage spikes that cause Low Component Count / screen monitors and driver viewable arcing and component failures. Competitive Module Cost / And Size automotive displays. devices that simply switch to a higher High Nits/Watt Efficiency New versatile dimming circuitry can frequency for striking do not have this real Can Operate Directly From a accept digital and analog control inputs and time control over output voltage, and Single Li-Ion Cell provides six different dimming modes that require much more attention to transformer Industries Safest And Highest design.
