Synchronous Switching Controller, any simple as this one?

hi, im on my way to build a simple buck regulator, but my knowledge and components availability are not that much (im in brazil)

but the schematics on most controllers are "too much" for me, too many components for this beginning project.

BUT, yesterday on my search for a simpler controller, i found this one:



http://datasheet.sii-ic.com/en/switching_regulator/S8533_E.pdf

it have fixed voltage versions (6v in my case), so its PERFECT for me. only need 3 capacitors, mosfet's and a inductor.

but i can't find this IC around, and i dont think thare is equivalent IC from another maker.

so, my question: anyone knows a synchronous buck controller simple as this one? or something on this level of complexity? low extra components are essentially

tnks in advance

 

Sign up here and input your input voltage range and output voltage and current and you will find several complete designs.

Note of caution: The pc board is important with switchers.
