DIY mobile power, car power, communications equipment and power supply.
Technical Parameters:
Module Properties: Non-isolated step-down module (BUCK)
Rectification: Non-synchronous rectifier
Input voltage: DC 5V-30V
Output voltage: DC 0.8V-24V (Adjustable, Output < Input)
Output current:Rated current is 2.5A,(5A Max, If current is larger than 2.5A, eEnhancement of heat dissipation is required.)
Note:Output voltage must be higher than Input Voltage
Input Voltage:2-6V(less than 3V,output power cut down)
Output Voltage:3.3V-9V adjustable(Input voltage must less than output voltage)
Output Current:Rated 2000mA (2.8V-3V input, 5V output, 1500MA output,(single lithium battery higher 2600MAH input,5V output, output current can up to 2000MA)
Note:Output voltage higher than 6V,Please connect power first,then connect load line
This module is based on a touch detection IC (TTP223B) of Capacitive type touch jog switch module . This module default output low, the low-power mode to mode; when a finger touching the corresponding position, the module will output high and returns low again touch. Mode is switched to fast mode; when for 12 seconds without touching

The RF receiver modules are widely used for data receiving and signal control. They are specified as preferred components in remote control garage, roller curtain, door locks, remote sensing, telemetry, industrial control and wireless security alarm industry.
Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);
2. Increased input reverse polarity protection diode;
3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).Particularly suitable for LED driver
*High-power LED constant current drive
*Lithium battery charger (including ferroelectric)
Adjust the light soft and stable, no flickering
PWM digital dimming, avoid rush current, protect your LED lights
Mainly use to adjust single color LED light lamps and Led Strip
