Some Applications

  • Rechargeable lithium-ion battery:
  • Drive high power LEDs
  • Charging curve as shown below: red for the current, blue for voltag


Battery Charging Method

  • 1. Make sure the recharge battery float voltage and charge current, input voltage of the module.
  • 2. adjust constant voltage regulator, the output voltage about 5V.
  • 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value;
  • 4. Adjust Constant regulator allows Output voltage reaches the float voltage;
  • 5. connected to the battery, try charging.
  • (1,2,3,4 step input connect power, output do not connect battery.)

 
LED Constant Current Driver Usage

  • 1. Make sure LED current and the maximum operating voltage;
  • 2. adjust constant voltage regulator, the output voltage about 5V.
  • 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value;
  • 4. Adjust Constant regulator allows Output voltage Reach LED maximum working voltage;
  • 5. Connected to the LED, test.
  • (1,2,3,4 take steps input connect power, output do not connected LED.)
