Conversor de tensão


Primeiramente gostaria de salientar que não sou o autor principal do conteúdo deste artigo. A minha intenção é de mostrar o que outros autores tem realizado (referenciando links para o conteúdo original) neste blog até como um guia pessoal para uso próprio e ainda compartilhar minhas anotações e pequenas modificações que realizo no conteúdo, desejando que possa ajudar mais alguém em algum lugar.
First and foremost, I take no credit for any of this post’s content. I am really just taking what others have done (which I have links to bellow) and am putting it on my blog for a personal reference and hopefully the small changes that I made to their guides will help someone somewhere.

Features 

 
  • Use imported and integrated switching regulator modules manufacturing,quality is stable and reliable.
  • Synchronous rectification,, the conversion rate is 96% or more, very low heat.Over voltage, over current, over temperature, short circuit, it can be auto protection,and can work in normal condition when restored.
  • Super-thin, small size, high efficiency, easy installation and use.
  • Input voltage: DC8-20V, (12V changes to 5V)
  • Output parameter: DC5V3A, 15W
  • It was micro usb output
 
 
Package
 
  • 100% Brand New 
  • 1 X DC/DC Converter 12V to 5V 15W
