imran khan, well the board has any inscriptions? (And I'm not talking about what a driver is, and what the key to this adapter?) I understand flew key (FET) resistors (current sensors) and if so then the driver (PWM) also spoiled sense to look for the scheme? the more I do not, my advice is buy a new adapter, or use a donor with the same parameters such (and write in Russian) |
