2 PCS 20W +- 5-24V Positive & Negative Dual Output Power Boost-Buck Converter

Description: Product Name: 2 PCS 20W +- 5V 6V 9V 10V 12V 15V 24V Positive & Negative Dual Output Power Supply DC DC Step-up Boost-Buck Converter module Packing list: 2 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 : 60.1 x 34.2 x 15.2mm 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 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 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) 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): 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
