Post subject: some information about BD9882F
Functions of the BD9882F are:(1)1ch control with Push-Pull;(2)lamp current and voltage sense feed back control;(3)Sequencing easily achieved with soft start control;(4)short circuit protection with timer latch;(5)under voltage lock out;(6)short circuit protection with over voltage;(6)mode-selectable the operating or stand-by mode by stand-by pin;(7)synchronous operating the other BD9882F or BD9882FV IC' s;(8)burst mode controllled by PWM an PC input.
The absolute maximum ratings(Ta=25℃) of the BD9882F can be summarized as:（1）supply voltage,vcc:15v;(2)operating tempreture range,topr:-40~+95℃;(3)storage temperarure range,tstg: -55~+125℃power dissipation,pd :550°mW for BD9882F and 650°mW for BD9882FV;(4)maxinum juction tempreture,tjmax:+125 ℃。
The electrical characteristics（Ta=25℃，vcc=7V） of the BD9882F can be summarized as:（1）operating current,icc1,16ma(max);(2)FB over voltage detect voltage,vovf,2.20~2.60V;(3)stand-by voltage h,vsth1.8~vccV;(4)stand-by voltage l,vsth -0.3~0.8V.
