+-5V 6V 9V 10V 12V 15V 24V Positive & Negative Dual DC DC Boost-Buck Converter (with Terminal, 5)

Input voltage 3.6~30V,output ±3~±30V adjustableMaximum output power: 20W (For details, please see the description at the bottom or ask us for information.)Conversion efficiency :69-88%Quiescent current: 3mA20W DC-DC Boost-Buck Converter working frequency 180KHZ.Operating ambient temperature : -40~+85 Degrees CelsiusSize : 60 x 34 x 15mmWeight : 33g(With terminal), 29g(no terminal)High efficiency up to 88%Built in Frequency CompensationBuilt in Soft-Start FunctionBuilt in Thermal Shutdown FunctionBuilt in Current Limit FunctionNote:1 In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA2 V- cannot be used alone, or no voltage output.But you can just use V+3 The startup current of the module is 2.5-3 times the operating current.4 Increasing the 1UF-10UF MLCC capacitor reduces the startup current(As shown below)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 range2 Output power can not be greater than the maximum load for a long time3 Input power must be greater than the output power, because the power consumption of the module itselfQ & A:Q1 : Why output voltage is less than the nominal voltageA1: Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very lowQ2 : 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.
