Feature
Module Properties is non-isolated boost converter with high converting efficiency of 92%Input voltage is DC 2.5V-6V, Output voltage is DC 4-12V which is adjustable and adjust the fixed resistor
The max output current is 1000mA, with overcurrent protection, low heat and long service life
Modules can independently adjust the voltage, max to 12V output, but to ensure that the output power is less than 5W
It will start undervoltage protection when the voltage is below 2.5V, which can protect the battery well and avoid excessive discharge and damage

Please note that:
This module is the fixed 5v output. If you need to adjust the output, please DIY the resistor R1, R2. [(R1+R2)/R2*0.6= VOUT]
Some applications:
DIY a mobile power, able to achieve a single lithium battery or two ordinary battery boost to 5V to charge the phone or PSP devices.
Front of a system power supply:due to the volume or other factors limit can only use a single lithium battery 3.6V
Note:Do not support the identification resistor products, such as Apple products
Package Include:
1x DC Boost Converter
