SKU: EB0044807
Favorites
Key Features
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. In order to obtain a more stable voltage, it is recommended that the output is greater than 10MA
2. V- cannot be used alone, or no voltage output. But you can just use V+
Applications:
ADC/DAC/Operational Amplifier Reference voltage
RS232 RS485 RS422 Bus
Audio equipment
Low power audio power supply
Car audio amplifier dual power board
LCD power supply
Instrumentation equipment
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 of the power consumption of the module itself
Q & A:
Q1: Why output voltage is less than the nominal voltage
A1: Input power supply power is too low. Test the input voltage with a multimeter, at this time of the input voltage is very low
Q2: Why is the negative voltage not output or the output too low?
A2: The negative voltage cannot be used alone. When using a negative voltage, the same load must be connected at the positive voltage terminal.
The maximum output power can reach 8W, but the maximum power will vary under different conditions. For details, please refer to the following table(10-80% of the maximum power is the most reliable):
8. Input DC 3.7-24V, Output ±12V
Input voltage: 3.7V/5V/6V/9V/12V/15V/18V
Maximum output current: 0.03-0.25A
Package includes:
5 x DC DC Boost-Buck Converter +/- voltage Dual voltage Module
