The BD9532EKN os a step down DC/DC converter controller for note PC,it's structure silicon monolithic integrated circuit.
Features of the BD9532EKN are:(1)built in H3REG DC/DC controller;(2)switching frequency variable(f=200kHz_600kHz).
The absolute maximum ratings of the BD9532EKN can be summarized as(Ta=25):(1)input voltage1,VCC:7*1*2V;(2)input voltage2,VDD:7*1*2V;(3)input voltage3,VIN:30*1*2V;(4)boot voltage,BOOT:35*1*2V;(5)boot-sw voltage,BOOT-SW:7*1*2V;(6)HG-SW voltage,HG-SW:7*1*2V;(7)LG voltage,LG:VDDv;(8)REF voltage,REF:VCCv;(9)output voltage,VOUT/IS+/IS-:VCCv;(10)ILIM/SCP/SS/FS/SLLM voltage,ILIM/SCP/SS/FS/SLLM:VCCv;(11)VREG voltage,VREG:VCCv;(12)EN input voltage,EN:7*1v;(13)power dissipation1,Pd1:0.5*3W;(14)power dissipation2,Pd2:0.75*4W;(15)power dissipation3,Pd3:1.75*5W;(16)power dissipation4,Pd4:2.00*6W;(17)operating temperature range,Topr:-10 to +100;(18)storage temperature range,Tstg:-55 to +150;(19)maximum junction temperature,Tjmax:+150.Note1:not to exceed Pd.Note2:instantaneous surge voltage,back electromotive force and voltage under less than 10% duty cycle.Note3:reduced by 4mw for each increase in Ta of 1 over 25(when don't mounted on a heat radiation board)Note4:Reduced by 6mW for increase in Ta of 1 over 25(when mounted on a board 70.0mm*70mm*1.6mm Glass-epoxy PCB.)Note5:Reduce by 14mW for increase in Ta of 1 over 25.(when mounted on a board 70.0mm*70mm*1.6mm Glass-epoxy PCB.)Note6:Reduce by 16mW for increase in Ta of 1 over 25.(when mounted on a board 70.0mm*70mm*1.6mm Glass-epoxy PCB.)
