G5567 offers high current capabilities, and is ideal for large screen lcd monitors panels and tv applications with 12v supply voltage. ordering information order number marking temp. range package (green) G5567qg1u 5567 -40 c~ +85 c qfn6x6-40 note: qg: qfn6x6-40 1: bonding code u : tape & reel pin configuration G5567 qfn6x6-40 pgnd pgnd lx1 vl ntc lx1 swi swo nc vgl drvn bstbk1 inbk1 inbk1 nc scl a0 hvs invl agnd comp lxbk1 lxbk1 outbk1 inbk2 gvoff outbk2 lxbk2 1 2 3 4 5 6 7 8 9 10 pgnd lxbk3 bstbk3 inbk3 re vghm vghp drvp 11 12 13 14 15 16 17 18 19 20 thermal pad 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 en pgnd sda outbk3 note: recommend connecting the thermal pad to the ground for excellent power dissipation.
