10pcs DD39AJPA 2 in 1 20W Boost Buck Dual Output Voltage Module 3.6-30V to 3-30V Adjustable Output

Description: Input voltage: 3.6~30V Output voltage: ±3~±30V adjustable Maximum output power: 20W Conversion efficiency :69-89% Quiescent current: 3-4mA Working frequency 180KHz Operating temperature : -40 to +85 a Size : 60 x 34 x 15 mm Weight : 33g Features: - High efficiency up to 89% - Built in Frequency Compensation - Built in Soft-Start Function - Built in Thermal Shutdown Function - Built in Current Limit Function 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 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.

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

Package Included: 10 x 3.6-30V to ±3-30V Adjustable Output DC Converter Board
