How about a microFlex?

[marcopolo]

Question to George at taskLED mainly, and wonderered about everyones thoughts also:

What about a miniature format driver for a single XR-E ,MC-E, or P4, P7 etc... Something to get a tiny enclosure size for say a helmet light or micro pocket torch etc...Or for making small tail lights out of the small LED: XP-E's.?

Preferably boost, for running on single LI-PO or 2xAAA, 2XAA etc...?
edit: just had a thought: 2xAA/AAA might be a wee bit small!! so ignore that bit!

It could be called a tootFlex or miniFlex, microFlex, miniMeFlex.

Marco.

Isn't the Micropuck small enough?

Isn't the Micropuck small enough?

And quite versatile.

That is a nice driver. I missed it.

Yes, but before getting too excited - look carefully at the application note efficiency curves.

It is very flexible but with efficiencies down as low as 65% in some configurations and generally less than 80%, hardly optimum for all topologies.

That's the price to pay when you want one driver that does it all, too many compromises and you pay for it with poor efficiency.

And it doesn't have your drivers programmable modes!

And it doesn't have your drivers programmable modes!

What? Do you want to have a 5-level brightness mode (e.g. UIB2) for just a taillight? You are hopeless and well beyond repair!

(I am also this kind of idiot... I have built a taillight long ago from a Luxeon 3W LED , using a Texas Instruments IC for its driver, but am planning to build some replacement instead...)

Is there any chance of a 0.55" diameter driver board in the (near) future?
