Problema incarcator SMPS

Recommended Posts

Buna! Am un incarcator WORX WA3727 de la o bormasina care scoate 21V la 500mA , 14W si am o problema... A cedat condensatorul de filtraj de dupa redresarea de 220v si a explodat IC-ul.E un integrat cu 8 pini iar pinii 6,7 sunt nelipiti . Atasez o poza cam handicapata facuta in paint pe fuga , poate cunoaste cineva IC .Daca e nevoie o sa detaliez mai mult schema .O zi buna!

Greu de spus....Sant multe integrate de acest gen....cu 8 pinii!!! Doar intr-un incarcator identic puteti gasi ce integrat este... :jytuiyu

Cumpara o sursa universala fara chopper tip UPS 01 si inlocuieste integratul cu ea, vei avea de lipit doar trei fire :da Sursa e vre-o 20 Lei si merge perfect acolo.

E incarcare prin impulsuri sau cum ii spune mai exact, nu stiu ca nu le am cu sursele in comutatie. Nu merge cu CC clasic. O sa-i fac maine niste poze.Multumesc pt raspunsuri!

Nu mai are nimeni nicio parere? Un ic asemanator macar chiar daca nu are la fel pozitionarea pinilor.
