Product Name: 20W Boost-Buck Dual Output Voltage 3.6-30V to +-3-30V Adjustable DC DC Step-up Boost-Buck Converter Module









Packing list:


 


1 PCS 20W DC DC Boost-Buck Converter Positive and negative voltage Dual voltage Module




 


 


Description:


 


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


 


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)


 


High efficiency up to 88%


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 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)






 


 


Applications


 




ADC/DAC/Operational Amplifier


RS232 RS485 RS422 Bus


Audio equipment


Low power audio power supply


Car audio amplifier dual power board


LCD power supply


Instrumentation equipment


Instrumentation multimeter


 


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.


 



 


 


 

The maximum output power can reach 20W, 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)
:

5V/±5V Output



6V/±6V Output


9V/±9V Output


10V/±10V Output


12V/±12V Output


15V/±15V Output


24V/±24V Output
