DROK LTC1781 100W DC/DC Step Up Converter 3-35V to 3-35V Voltage Switching Regulator with Voltmeter USB Interface for DIY Mobile Power Supply Charge IPad/IPhone

Parameters:
Module Properties: Non-isolated Boost Module
Input Voltage: DC 3-10V (low input voltage application); 6-32V(high input voltage application), can be selected by the jumper
Output Voltage: DC 3-35V(Continuously adjustable, defualt 19V)
Input Current: max 10A(need heat dissipation when input current is over 6A)
Output Current: max 6A(need heat dissipation when output current is over 5A)
Quiescent Current : 15mA, not include the current of voltmeter
Working Temperature: -40~+85 degrees
Operating Frequency : 280KHz
Conversion Efficiency : up to 96%
Protections: over current protection(when input exceeds 12A, automatically reduces the output voltage) short-circuit Protection(input 15A fuse, double circuit protection) no input reverse polarity protection, if necessary, please connect diode with input in series.
Identify Resistance : Tablet PC, iPad, iPhone (some phones identify circuit is different, need to be adjusted)
Voltmeter minimum resolution : 0.05V(10V or less automatically switch the decimal point)

Instructions:
1. Voltmeter power options : Select power the voltmeter from input or output by jumper on the board, short the jumper to reduce the loss of the voltmeter. Remove the jumper cap, the voltmeter does not work.
2. USB output port: USB interface is connected to the output directly, with the identify resistor. Please make sure the USB output voltage is consistent with the voltage of your products. Otherwise it will burn your digital products.
3. Switch to display the voltage, VI: input voltage; VO: output voltage.
Please note: This DC converter is single output, the output voltage of the USB port is the same as the output voltage of the module, if your load is USB device, please make sure the module's output voltage is set at 5V.
