Applications: 6-15V Low Power Motor 6-15V LED Lighting Hard drive power supply 9V 12V 15V Routers and network equipment Wireless communication equipment 315M 433M Wireless remote controller Attention : This is a DC-DC voltage converter module,Must be noted when using: 1 Input voltage can not be greater than the maximum input range 2 Output power can not be greater than the maximum load for a long time 3 Input power must be greater than the output power, because the power consumption of the module itself Modify Parameter Description: 1.4A 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 Degrees Celsius. The power MOSFET wake up when the junction emperature drops 30 Degrees Celsius under the OTP threshold temperature The master chip is FP6291 Input voltage 3~6V, output 6-15.5V Maximum input current : 1.4A Long-term work Current : 1A Conversion efficiency : 79-90% Input: USB Male Interface, DC 3-6V; Ouput : 2 PIN XH2.54, DC 6-15.5V; If input dc 5v,output 6-15.5V Adjustable Power : Maximum 7W DC-DC Boost module working frequency 1.0MHZ Operating ambient temperature : -40~+85 Size: 4.7x1.6cm/1.85x0.63inch Quantity: 1 Pc Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
