Protection : Over current protection(OCP) Over voltage protection(OVP) Short circuit protection(SCP) Over temperature protection(OTP) Pin description: Vi : Input positive(+) GND : Input and Output negative(GND/-) Vo : Output positive(+) Output 3.7V : Input voltage: DC 2.6 - 3.6V output voltage: DC 3.7V±3% Maximum output : 3.7V/1200MA(See the table below for details) Output 5V : Input voltage: DC 2.6 ~ 4.5V Output voltage: DC 5V±3% Maximum output : 5V/1200MA Output 12V : Input voltage: DC 2.6 ~ 6V Output voltage: DC 12V±3% Maximum output : 12V/500MA Package list: 1 * Module Note: This is a DC - DC voltage converter module, please pay attention when using: 1, The input voltage should not be higher than maximum input range. 2, The output power cannot be higher than the maximum load for a long time. 3, The input power must be higher than output power, because of the power consumption of the module itself. FAQ: Q: Why the output voltage is lower than the nominal voltage? A :Because the input power is too low.Use a multimeter to test the input voltage, the input voltage is very low at this time.
