DC-DC Adjustable Step-Up Boost Converter — 3V–35V Input to 4V–40V Output
An adjustable DC-DC step-up (boost) converter module providing continuously adjustable output voltage from 4V to 40V from a 3V–35V input, via an onboard trimmer potentiometer. The boost converter steps up the input voltage to a higher output voltage, making it suitable for applications requiring a higher voltage than the available supply — such as boosting a 3.7V LiPo to 12V, or a 5V USB supply to 12V or 24V. The wide input and output voltage range makes this module versatile for a broad range of power supply and embedded system applications.

- USB to 12V/24V: Step up 5V USB power bank output to 12V or 24V for solenoid valves, LED strips, and 12V/24V accessories
- Solar Power: Step up low-voltage solar panel output to 12V or 24V for battery charging and electronics supply
- Automotive Boost: Step up 12V vehicle supply to 24V for 24V accessories and equipment in 12V vehicles
- DIY Bench Supply: Adjustable high-voltage output module for a DIY bench power supply requiring output above the input voltage
FAQ
Q: Can the output voltage be set lower than the input voltage?
A: No. A boost converter can only step up voltage — the output must always be higher than the input. For step-down (buck) conversion, use an LM2596S or MP1584EN module instead.
Q: What is the maximum output current at 12V from a 5V input?
A: Output power is limited by input current and efficiency. At 5V input and 93% efficiency: P_out = P_in × 0.93. If the input can supply 3A at 5V (15W), output at 12V is approximately 15 × 0.93 / 12 = 1.16A. Higher output current requires a higher-current input source.
