I have a broken switching power supply that has a chip in it labeled: TL494CN RLFU8940 It's a 16 pin dip. I'm guessing it might be bad because the power supply doesn't work, and I've checked every component I know how to check. little david dt@yenta.alb.nm.us -- It's not sold in any stores...now find out why. Offer void when precluded by common sense.

My IC Master lists this as a switching regulator circuit. There are many suppliers. With the TL in front, there are the following: Motorola and Texas Instrument are listed. You should be able to order them from a parts supply house.

Au contraire -- it is widely available. I have several that I bought over the counter at a store right here in Honolulu. If no store, then mail order should take about a week. JDR or Digikey must have it. -- Regards, Alan Whinery whinery@hale.ifa.hawaii.edu
