Sursa 5V pentru microcontroler

Recommended Posts

Tensiunea de intrare provine de la doua baterii de 12V inseriate,  in diferite faze de incarcare, descarcare,

si se afla intr-un UPS.

Exclud alimentarea dintr-o singura baterie pentru evitarea unui dezechilibru in timp.

 

Tensiunea de iesire 5V si maxim 1A.

 

Care ar fi solutia optima ca si costuri, randament, stabilitate in timp ?

Daca lucrezi SMT atunci cauta un TPS de la Texas. 1-2A ii obtii usor pe o suprafata de 400mm patrati. Multe accepta pana la 48V intrare. Cu randament de 90 si ceva la 100. Poti sa-ti faci designul online cu Webench.Altfel, sunt module pe eBay la preturi de nimic.
