Availability date:
This DC-DC step down module is a low-voltage switching power supply which makes the energy losses very small. It is step-down so the output voltage is less than the input voltage. While operating in sync mode, the output voltage can be achieved as low as 1 V with very good efficiency up to 96%.
Having very small dimensions and supporting a current up to 1.8 A continuously, it can be easily included in a wide range of projects.

foarte bun, super exceptional.
perfect pentru incarcator USB 12V
L-am folosit pentru un incarcator alimentat la 12V, cu 2 iesiri USB. Foarte multumit. 5 lei + cateva fire si un conector USB cu 2 porturi: un incarcator USB excelent si ieftin pentru orice smartphone.

eu am cumparat 3bucati, singura problema e chinuiala la reglaj (daca se pune un potentiometru multitura este perfect)
Slab
Desi chip-ul ar trebui sa suporte 3 A pe iesire la peste 1A placa se incalzeste foarte mult , randamentul e in zona 80-85%. La 2A dupa un minut intra in protectie termica. Problema e doar cu incalzirea , nu apare limitare in curent nici la 3A , e posibil sa mearga daca lipiti placa pe un radiator. Aveti grija cu semireglabilul , se rupe foarte usor.
