Mini sursa step down reglabila IN:4.5V-28V si 1.8V 2.5V 3.3V 5V 9V 12V adj

Mini sursa step down max 28V IN si max 3A - (2A fara racire)



Sursa reglabila dimensiune foarte mica (22mm x 11mm) + tensiuni fixate (1.8V 2.5V 3.3V 5V 9V 12V) cu 2A cu racire ambientala si max 3A cu racire "fortata" (radiator si/ventilator)

Nota: Pentru a folosi tensiunile fixate, trebuie sa "taiati" (intrerupeti) traseul de la ADJ (vezi poze)



Nota: La sarcini de peste 2A sau peste 75-80C (temperatura integratului), necesita racire suplimentara cu un mic radiator sau mic ventilator.
