Hi everyone.
I've just come across a product I've not seen before and wondered if it could help out on the myriad LED matrices people on here seem to love.
It's called the TOP249 and has MOSFET and PWM control built in, datasheet is here

I don't understand enough about components to know if this would be of any use, the datasheet just uses words I hear bandied around here a lot
