lv5011md no.a2201-8/10 functional description lv5011md is an led driver ic that oper ates directly from the rectified ac voltage. lv5011md controls brightness of the led by controlling a peak current of the internal mosfet. 1. peak current control lv5011md detects the current of intern al mosfet as shown in the following diagram. the current that flows into mosfet is a triangular wave shown in the diagram. the current peak value is determined by the relationship between the reference level and cs voltage. this relationship makes power factor correction (pfc). cs voltage is used by internal comparator to compare to the reference level. lv5011md controls the peak value of mosfet current. here, the reference level is lower value of either ?ref_in? or ?vref(0.605v)?. the peak value of mosfet current (ipk) is determined by : in the case of ?ref_in < vref(0.605v)? rcs in ref ipk _ ? in the case of ?ref_in > vref(0.605v)? rcs v ipk 605 . 0 ? 2. bleeder current cuircuit for triac dimming lv5011md contains the bleeder current circuit for triac dimming. please connect out2 to the external mosfet gate and connect the resistor ?rd? to its drain. 2-1. operating voltage setting out2 pin is controlled by setting value on acs pin. when acs pin voltage is below 3v, out2 is high and external fet is turned on. the bleeder operation threshold of the rectified ac is determined below. vac_bleeder = v r r r 3 4 4 3 ? ? 2-2. bleeder current setting bleeder current is set by rd. please calcu late rd value based on triac dimmer. waveforms diagram vac voltage is low, out2 is high voltage. triac dimmer,off bleeder circuit,on(out2;high) off on out2 vac vacs(3vtyp) off off on a cs on min on on on built-in fet gate min on + - - clk reset q ref_in cs out vref (0.605vtyp) rcs r1 r2 l rectified ac voltage fet current m1 drain source rectified ac voltage fet current ref_in out (fet gate) t on off ton toff vref (0.605vtyp) reference =ref_in reference =0.605v reference =ref_in reference r1,r2 : external resistor for ref_in pin setting rcs : external resistor for current sense m1 : internal power mosfet
