Despre regulatoare

Regulatoarele Step Down sau convertoarele buck sunt convertoare de tensiune care primesc la intrare o tensiune mare, de obicei cuprinsă între 4.5 și 24 de volți și produc la ieșire o tensiune fixa de 3.3 sau 5 volți. Cu alte cuvinte, regulatoarele Step Down îți permit să alimentezi un microcontroler (5 sau 3.3V) folosind un acumulator LiPo sau o cutie de baterii de 7,2V. Spre exemplu, poți să alimentezi o placa Arduino cu 5V dintr-o sursa de alimentare de 9V folosind un regulator Step-Down.

Regulatoarele Step-Up sau convertoarele boost sunt convertoare de tensiune care primesc la intrare o tensiune mică, de obicei cuprinsa intre 2.5 și 9V și produc la ieșire o tensiune mai mare decât cea de intrare. Exista o gama variata de regulatoare, cu ieșire fixă sau cu ieșire reglabilă. Spre exemplu, poți folosi regulatoarele Step-Up pentru a alimenta o placa Arduino cu 5V sau orice alta componentă folosind o sursa de tensiune mica, spre exemplu o baterie de 1,2V.

Regulatoarele Step-Up / Step-Down primesc la intrare o gama larga de tensiuni si produc la iesire o tensiune fixa. Spre exemplu, un regulator step-up / step-down poate produce o tensiune fixa de 5 sau 3.3V primind la intrare o tensiune cuprinsa intre 2.7 si 11.8 volti. Practic, ele au capacitatea de a converti tensiuni mari dar si tensiuni mici.

Cum se alimentează o placa Arduino dintr-o baterie de 1.2V?

O placa Arduino poate fi alimentată direct dintr-o baterie de 1.2V folosind un regulator Step-Up de 5V U1V11F5 și un breadboard. Regulatorul se conectează….
