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 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 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,a t 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.
