Description: Input voltage: 3~24V, output optional: 5V/6V/9V/10V/12V/15V/18V24V Maximum output power: 1-8W (For details, please see the description at the bottom or ask us for information.) Conversion efficiency: 70-90% Quiescent current: 3-4mA Accuracy: Positive voltage 3% Negative voltage 5% 8W DC-DC Boost-Buck Converter working frequency: 400KHZ. Operating ambient temperature: -40~+85 Degrees Celsius Size: 42 x 24 x 15mm Weight: 10g Feature: 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): 1.
