MC34063 - DC TO DC CONVERTER

Recommended Posts

Guest Kimnotyze

Uitati aici un controller tare dragut. DESCRIERE:UTC MC34063 este un convertor C.C. - C.C.Acest dispozitiv contine o referinta compensata termic a benzii interval, un oscilator duty-cycle, un driver si o iesire de curent mare. Poate fi folosit pentru surse in comutatie coboratoare, ridicatoare sau ca inversor de tensiune in comutatie.Pentru numai 2 LEI face urmatoarele:*Iesire intre 3.0V si 40V.*Limitare a curentului in caz de scurt-circuit.*Consum mic in stand-by.*Iesirea comuta pana la 1,5A fara tranzistori externi.*Lucreaza in banda de frecventa 100Hz pana la 100kHz.L-am vazut intr-o revista a unui magazin de electronice, era o schema ridicatoare de la 12V , pentru auto. Schema era foarte simpla si pe langa cateva componente discrete si traful toroidal, avea si acest circuit mic si destept.Circuitul se gaseste pe piata si costa doar 2 lei!Pofta buna!

Salut. Acest cip se foloseste cu succes si in programatorul DIY Willem. Practic face Vpp de care ai nevoie, 12.5V,21V sau 25V. Bun cip, si la pretul asta... :tonqe: Cu stima,Costel
