Internal Optimize Power MOSFET 

High efficiency up to 90% 

Built in Frequency Compensation

Built in Soft-Start Function 

Built in Thermal Shutdown Function

Note:

1 Due to the diode partial pressure, the voltage of -Vo is lower than +Vo

2 In order to obtain a more stable voltage, it is recommended that the output is greater than 1MA

3 -Vo cannot be used alone, or no voltage output.But you can just use +Vo 

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

Q & A:

Q : Why output voltage is less than the nominal voltage

A : Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
