Review on Automatic Step Down Regulating Constant Regulator by Jeff Alradwan

Revainrating 3 out of 5

DC current but can not withstand more than 2A

My block is doing its job, but around 2:00 this block gets insanely hot and shuts down, so hot it melts the glue left on it from the previous project. Definitely need a fan for higher voltage and current.

Pros
  • Using boost buck chip as main controller, external MOS tube 60V 75A as switch, 60V 5A SS56 double Schottky rectification, 60V rated voltage, superior to the immature market program XL6009 / LM2577 (many pressure value of the device is not enough, the pressure value of the MOS tube and Schottky diode must be greater than the input value plus input voltage);
Cons
  • There are problems
