Input voltage 3~6V
 output 12V 
Maximum input current: 1.2A
Long-term working current: 1A 
Conversion efficiency: 80-90% 
The maximum input current can reach 2A when the resistor is removed. However, the IC has the function of "over temperature protection". When the internal junction temperature exceeds 150°C, the power MOSFET will automatically turn off. 
When the connection temperature drops to 30°C at the OTP threshold temperature, the power MOSFET will wake up. The starting voltage is 2.8V and the output current is 50mA.

Be careful: This is a DC-DC voltage converter module. When using it, you should pay attention to:
1. Input voltage can not be greater than the maximum input range 
2. The output power can not be greater than the maximum load for a long time The input power must be greater than the power of output due to the power consumption of the module itself
