Sal vreau sa fac si eu aceasta sursa in comutatie http://sound.westhost.com/project89.htm (varianta cu feedback) si am 4 probleme :

 

1. Nu am gasit de cumparat sg3525 si am luat uc3525(Fairchild) si nu stiu daca ii compatibil la pini cu sg3525 (cred ca e dar mai bine intreb :)) ca am luat datasheetul lui (de pe http://www.datasheetcatalog.com) si acolo nu prea scrie mai nimic. :((

 

2. Unde gasesc un transormator teroidal de ferita , si cat trebuie sa fie de mare pt +/-30V si 400W (daca nu teroidal cel din surse de comp)?

 

3. Ce mosfeturi recomandati ca is mai multi insiruiti si cate pe ramura (eu ma gandeam 2 x 3 = 6 BUZ11A)?

 

4. Unde gasesc Ultra Fast Brige de 35A ca am incercat la Vitacom si Ret si nu au, am gasit numai diode UltraFast dar erau <1A ?
