Default best way for -12 V

I need -12V for an op amp to generate a +/-10V signal. I have two national smps for 12 and 5 v that i use for everything, the lm25576. i will need approx 200 mA @ -12V, what i would like to maximize efficiency, board space, and cost.

Read the component datasheet. Page 21 if you are unsure what you are looking for.
