mp3 player

Recommended Posts

Chestia e cam hopeless da' incerc si eu...


Se da un mp3 player trekstor i.beat organix.


Legat la calculator e ok, pe post de usb storage. Independent imediat dupa ce porneste se stinge.


Acumulatorul e ok, dar cit timp e pe acumulator una din tensiunile interne (1.5) variaza (pe multimetru vad intre 1.3 si 1.6V in timp ce booteaza). Mai e o tensiune de 3V dar aia e stabila.


Dupa ce gasesc o lupa poate gasesc si stabilizatorul de 1.5V - pina atunci m-ar interesa o schema de la ceva de genul asta sau cam ce integrate se folosesc


Pina acuma am gasit unul din stabilizatoarele de 3V (e din familia LT3467)
