Oto lepsze foto.
Raczej nie jest to podany przez Ciebie układ, ale pinout jest bardzo podobny.
GND, VIN, VOUT się zgadzają , EN OC PG być może także
EPSON prawdopodobnie użył lokalnego producenta ROHM ?
Ale wskazówka bardzo cenna , bo ten układ można zaadoptować na "pajączka" o ile fazy sygnałów analogowych będą zgodne.
Może ktoś znajdzie DS oryginału ?
