Input voltage 3-6V, output 12V
Maximum input current:1.2A;Long-term work Current : IA;1.2A current limiting resistor,Remove the resistance, the maximum input current can reach 2A.
But IC have "Over Temperature Protection" Function.It will turn off the power MOSFET automatically when the internal junction temperature is over 150 °. The power MOSFET wake up when the junction emperature drops 30 ° under the OTP threshold temperature.
Conversion efficiency:80-90%;DC-DC Boost module working frequency 1.0MHZ.
2.54mm pin pitch,Arduiuo UNO DUE Breadboard FPGA / CPLD Development Board friendly.
