Halogen dimmer IC chip! Does it exist?

[RobertRoss]

Hi,
I am looking for a dimmer IC chip very similar to the SLB 0587 originaly from Seimes but now available from Infinion under another part# which I can't find.

This chip, when adding a few passive components to it, act as a halogen dimmer capable of dimming an inductive load (The transformer in a halogen fixture in this case).

Does anyone know where I can get this chip!

All help is greatly appreciated!

Robert

Infineon no longer makes this chip, but it did at one point with the same part number ( SLB0587 )

Internation Rectifier makes similar parts, like the IR2161, which is very new, here is an application note with PCB laout and other good information:

the data sheet for just the IC :

They also have an established line of IC's for this purpose:
