Inherited from Vulgar Latin *plattus (“flattened”), from Ancient Greek πλατύς (platús). Given that this word is attested rather late in time, such as in Cervantes' Don Quixote of 1605, it's theorized that it may have been borrowed from Portuguese (where the phonetic shift of the Latin consonant cluster -pl- to -ch- is regular; in Spanish, it generally becomes -ll- instead); alternatively, it may have been a colloquial word used by the people that did not make its way into written documents prior
