20W +- 5V-24V Dual Output DC DC Boost-Buck Converter module

• Input voltage 3.6~30V,output ±3~±30V adjustable
• Maximum output power: 20W
• 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)

Features

• 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)
