Step Down Buck Converter with MP1584

what advantage of using mp1584 compared lm2596?

when @ breakout board mp1584 looks unfamiliar (no capacitor, no coil)



(1) mp1584
(2) coil (4,7µh)?
(3) capacitors?

i assume #2 coil.   if curious can trace-out connections (an ohmmeter can help), draw schematic, , compare manufacturer's recommended circuit shown on datasheet.  

the coil measure short (or nearly  zero ohms) ohmmeter.

the black part above ic didn't mark output capacitor.
