Product Description


  • Lithium battery charger
  • LED Driver


  • Do not combine connection of input GND and output GND, These are separated!


  • High power module, high efficiency, 5A max current, low ripple
  • Three main applications:
    • Used as an ordinary step-down modules with overcurrent protection capabilities.
    • To charge various voltage lithium batteries, lead-acid batteries, nickel-cadmium or nickel-metal hydride batteries (battery), charger for solar panels, wind turbines and other similar applications.
    • As high-power LED constant current driver module.
  • Has constant voltage and constant current modes, the indicator leds indicates which mode the module is currently operating in.
