Digikey and Ztex new (?) circuit

[KenBar]

I was putting an order together in the April/May 2002 Digikey catalog and noticed that they had a chip for under 1 buck that is programmable and functions down to .8 volts. This is specifically for LED circuits for flashlights and/or displays on devices the blurb said.

This was in the transistor section ( very beginning of second section) and in the ZTX groups. Anyone had any experience with this? It said it was new for XTX.

I was going to toss in an order for a dozen to play with although it said a demo was available. This almost seems too cheap.

Check out the discussion and design using this IC at:Zetex ZXSC300 single-cell LED driver

Construction hints and assembly notes are at:
5th Column official web site.

Not too sure if I got the title of the web page correct. There are many others messages about this IC and construction hints, installation into a mini mag here in LED, Electrolumenescent and Lasers.

Good grief!
You would think after looking at that thread all those months I would have remembered..
