• Lithium battery charger
  • LED Driver


  • Do not combine connection of input GND and output GND


  • High power, high efficiency, 5A, low ripple;
  • Three main functions:
    • use as an ordinary step-down modules with overcurrent protection capabilities;
    • as the value of various voltage lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery) charger for solar panels, wind turbines and other occasions;
    • used as high-power LED constant current driver module;
  • Having a constant voltage and constant current modes, the indicator light indicates which mode is currently in the module;
  • When used as a lithium battery charger, you can set the float voltage and charge current, it has a light finger
  • It is shown being charged or has been filled;
  • Current limiting protection, output short circuit will not even burn module.

    Using it to step 12volt batteries down to 5 volts. Seems to be about 90% efficient. Way better than any linear regulator. Constant current mode means it should be a great led driver too.
