DC-DC Converter 5V to 3.3V/±25V Adjustable Power Module
DC-DC Converter 5V to 3.3V/±25V Adjustable Power Module
DC-DC Converter Power Supply Module — 5V Input, Multi-Voltage Output
Take full control of your electronics projects with this versatile DC-DC Converter Power Supply Module. Designed for hobbyists, engineers, and makers alike, this compact board accepts a 5V input and delivers three flexible output channels — including a fixed 3.3V rail and two fully adjustable bipolar outputs ranging from ±4.5V to ±25V. Whether you're powering op-amps, sensors, microcontrollers, or custom circuits, this module gives you the output flexibility you need in a single, tidy package. Made in Mainland China.
Key Features
- Three Output Channels: Fixed 3.3V output plus two independently adjustable bipolar outputs (default ±12V and ±5V) to suit a wide range of electronic devices.
- Wide Adjustable Voltage Range: Outputs 1 and 2 are tunable within ±4.5V to ±25V, giving you the freedom to dial in exactly the voltage your application demands.
- Dual Input Interface: Choose between a Type-C or standard DC barrel jack input — whichever suits your bench or field setup best.
- Stable & Efficient Power Delivery: Rated at 5V / 2A input, with up to 300mA output per adjustable channel and 200mA on the fixed 3.3V rail for reliable, steady operation.
- Optional Shell/Enclosure Compatible: Supports add-on enclosure components for improved durability, protection, and a cleaner finished look.
- Compact PCB Footprint: 102mm × 65mm board size makes it easy to integrate into enclosures, breadboards, or custom project boxes.

Frequently Asked Questions
Q: What input voltage does this DC-DC converter power supply module require?
A: This module is designed for a 5V DC input at up to 2A. You can power it via a Type-C cable (from a USB power adapter or power bank) or through the DC barrel jack — whichever is more convenient for your setup.
Q: Can I adjust both bipolar output voltages independently?
A: Yes! Output channels 1 and 2 are each independently adjustable within a ±4.5V to ±25V range. Output 1 defaults to ±12V and Output 2 defaults to ±5V. The third output is a fixed 3.3V rail. This makes the module ideal for powering a wide variety of components from a single 5V source.
Q: Is this module suitable for breadboard or prototyping use?
A: Absolutely. With its compact 102mm × 65mm PCB and accessible terminal outputs, this converter integrates well into prototyping environments, custom enclosures, and lab benches. The optional shell accessory further enhances its durability and aesthetics for more permanent installations.
Q: How much current can each output channel supply?
A: Each of the two adjustable bipolar outputs (Output 1 and Output 2) can supply a maximum of 300mA. The fixed 3.3V output (Output 3) provides up to 200mA. These are suited for low-power ICs, sensors, op-amps, and microcontroller peripherals.
