Salut, de ce este nevoie de o comanda asa complicata pt LED-uri ?

ATMEGA48PA SI AS3693B

 

Si daca ati intalnit tranzistorii de comanda asa supraincalziti !

Poate este genul acela de backlight cu LED-uri care se aprind și se sting in functie de continutul imaginilor .De exemplu ,in zona care afișează negru ,se sting LED-urile .

Cât despre temperatură ... la ce capsulă au acei tranzistori ,și in ce conditii functionează , nici nu mă mir că se supraincălzesc .
