Internal Optimize Power MOSFET
High efficiency up to 90%
Built in Frequency Compensation
Built in Soft-Start Function
Built in Thermal Shutdown Function
Built in Current Limit 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 15MA
3 -Vo cannot be used alone, or no voltage output.But you can just use +Vo
Applications
ADC/DAC/Operational Amplifier
RS232 RS485 RS422 Bus
Audio equipment
LCD power supply
Instrumentation equipment
MCU Board
Motor Power
Instrumentation multimeter
Wifi/Router/Ethernet devices
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
