Question

Hey Guys

I'm building a bipolar power supply, but the ic i need (TC1044SPCA), is not available.
What should I use to replace this ic? What's a good alternative?.

Cheers,
Jovl

You could build a voltage inverter like this and use both outputs (+9v from top track, -9v from fourth track). Uses an ICL7660S (the S is important!!) which are common and inexpensive. I bought ten for like $3.

I believe someone in the comments of that post actually did this. It will (should) be exactly what you need.

EDIT actually, here.

max1044 looks like a pin for pin replacement, according to the datasheets the max1044 max input voltage 10.5v, tc1044 max input voltage 12v.
tc1044scpa are available at farnell uk, mouser & ebay
