I would like a small led driver circuit schematic drawn up in altium designer.
It should supply 9 x 5050 warm white led's.
It should use easy to find components from digikey or rs-components for example.
It can use a dedicated driver, op amp, or whatever is sutable.
I would prefer not to use current limiting resistors to burn off power as it is supplied from a battery and should be fairly efficient.
It will be run off a single cell li ion battery.
Please provide component list and values.

Thankyou for your bids.
It is a low budget job of around $30 but it is a great starting point for a first time freelancer.
Cheers
