20W DC-DC 3.6V-30V to +/- 5V 6V 9V 10V 12V 15V 24V Dual Power Supply Positive Negative Dual Output Power Supply DC DC Step-up Boost Buck Voltage Converter Module

Product description Dual Power Supply Positive Negative Dual Output Power Supply DC DC Step-up Boost Buck Voltage Converter module
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. Input voltage 3.6 ~30V, output ±3~±30V adjustable Maximum output power 20W (For details, please see the description at the bottom or ask us for information. ) Conversion efficiency 69-88% Quiescent current 3mA frequency 20W DC-DC Boost-Buck Converter working frequency 180KHZ. Operating ambient temperature -40~+85 Degrees Celsius Size 60 x 34 x 15mm Weight 33g (With terminal), 29g (no terminal) Feature 1 Built in Frequency Compensation Feature 2 Built in Soft-Start Function Feature 3 Built in Thermal Shutdown Function Feature 4 Built in Current Limit
Function Note: 1 In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA 2 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) See More
