    IR3553 / IR3555 pin compatible?

    Hi I have an out of warranty Graphics card I wish to attempt a repair on. The Card has died twice during it's warranty and again just after warranty ended (not your fault!), I suspect underpowered IR3553 might have been responsible each time. (They develop a short when broken)

    I am wondering if it is possible for me to replace all the IR3553 with IR3555, i.e. are they pin compatible.

    I understand the IR3553 is 4mm x 6mm and the IR3555 is 6mm x 6mm, but the GPU seems to have extra pin space for fitting the larger chips, there are large solder pads underneath each chip which allow for different chip sizes. I have attached an image showing the 4mm x 6mm IR3553 on the circuit board.

    Hello Karrana,

    IR3553 / IR3555 are not pin compatible.
