Contest. Barbolight U-09 Mk.II as reward.

[Barbarin]

Just for electronic masters.

I'm looking for a buck current regulator, 900 mA. Minimun surface and minimun number or parts required. Max Vin arround 13 V. Min efficiency. 90%
It would be perfect if it could be programmed at x Vin to enter into economy mode ( 90 mA). No shut down required.

I will pay all the expenses of making the prototype, and will send a U-09 Barbolight to the winner.

Regards,
Javier Lopez

Barbar,

Is a contest or a request? If it is the latter, I'll do it.
Give me a week and I'll have a schematic drawn. Contact me at
