led driver, altium schematic design

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.
