| product number: AS3693B-ZTQW 16 channel high precision led controller for lcd backlight description: the as3693b is a 16 cannels high precision led controller with build in pwm generators for driving external fets in lcd-backlight panels. external clock and synchronizing inputs allow the synchroni zation of the lcd backlight with the tv picture. local dimming and scan dimming is supported by 16 independent pwm generators with programmable delay, period and duty cycle. three free configurable dynamic power feedback circuits make the device usable for white led as well as rgb backlights. build in safety features include thermal shutdown as well as open and short led detection. all circuit paramet ers are programmable via i2c or spi interface. features: ? 16 independent led channels ? external fet control and current sensing ? output voltage sense up to 50v ? absolute current accuracy 0.5% ? output slew rate limit ed to reduce emi ? current programmable with external resistor ? 16 independent pwm generators with 12 bit resolution ? h-sync, v-sync inputs to synchronize with tv-set ? three independent power feedback for r-, g-, b-supply regulation ? build in 5v shunt regulator ? i2c or spi interface with 5 bit device address ? fault interrupt output ? open led detection ? short led detection ? temperature shutdown ? package eptqfp64 free datasheet http:///
