al5809 document number: ds36625 rev. 5 - 2 8 of 16 www.diodes.com december 2016 ? diodes incorporated al5809 application information (c ont .) power dissipation the maximum ambient temperature range of the al5809 is de termined by its power dissipation and thermal impedance of the pcb onto which it is mounted. its junction temperature must be kept equal to or less than +125c. th e power dissipated is determined by the led current ver sion that has been selected (15, 20, 25 30, 40, 50, 60 , 90, 100, 120 or 150ma) and the difference between the input voltage and led chain vo ltage. v inout * i led in a typical 12v system, the input voltage can vary betw een 11.4v and 12.6v. the recommended minimum v inout voltage of 2.5v enables the al5809 to drive 2 led in series from the 12v rail (assumin g v led <3.25v). the al5809s power dissipation under minimum input voltage cond itions will be: v in out * i led = (11.4-6.5) * i led so for the 20ma al5809-20pi under these conditions thi s equals: 4.9v * 20ma = 98mw under maximum input conditions (12.6v) the al5809s powe r dissipation will be: v inout * i led = (12.6-6.5) * i led so for the 20ma al5809- 20 qpi this equals: 6.1v * 20ma = 122mw so there is a large difference in power dissipation of the line ar led driver between minimum and maximum battery voltages. and care must be taken to calculate expected power dissipations and then d etermine the suitable pcb material and layout. see figures 9 , 10 and 11 for graphs showing power dissipation and maximum v inout , for different currents and pcb material. maximizing the ar ea and mass of the ground plane and additional vias between the pad of the out pin will improve th e thermal impedance ( ? ja ) of the al5809. 0.00 0.25 0.50 0.75 1.00 1.25 1.50 0 25 50 75 100 125 power dissipation (w) ambient temperature ( c) power dissipation [w] vs. ambient temperature [ ?c] for pdi-123,sod-123 on fr4, and pdi-123 on getek sod on fr4 ( max tj=145) pdi on getek ( max tj=145) pdi on fr4 ( max tj=145) figure 9 power dissipation vs. ambient temperature @t j = + 145 c 0 10 20 30 40 50 60 0 25 50 75 100 125 150 maximum v inout [v] ambient temperature [ c] maximum v inout [v] vs. ambient temperature [ ? c] for pdi on fr4 current options (referred by apps board fr4, 2-laye r, 0.69"x0.76") pdi on fr4 15ma pdi on fr4 20ma pdi on fr4 25ma pdi on fr4 50ma pdi on fr4 90ma pdi on fr4 150ma pdi on fr4 40ma pdi on fr4 60ma figure 10 maximum v inout vs. temperature 0 5 10 15 20 25 30 35 40 0 25 50 75 100 125 maximum v inout [v] ambient temperature [ c] maximum v inout [v] vs. ambient temperature [ ? c] for current option on pdi fr4 board (referred by apps board fr4, 2-layer, 0.69"x0.76" size ) sod on fr4 15ma sod on fr4 20ma sod on fr4 30ma sod on fr4 40ma sod on fr4 50ma figure 11 maximum v inout vs. temperature
