2.8V-5.5V to ±12V DC Dual-Output Power Module (Positive & Negative Voltage Converter)
Deliver balanced dual-rail power to your high-precision analog circuits with the industrial-grade 2.8V-5.5V to ±12V DC Power Module. Engineered as a high-efficiency charge-pump and switching regulator combination, this specialized board takes a low-voltage single-cell input and splits it into simultaneous, symmetrical positive 12V and negative 12V DC output rails.
Standard microcontrollers and digital systems run on simple positive voltages, but high-end analog hardware—such as operational amplifiers, data converters, audio pre-amplifiers, and industrial instrumentation sensors—requires both a positive and a negative power rail to process signals without clipping. This module acts as the perfect compact power vault, generating a stable dual-rail split grid from standard lithium-ion batteries or 5V USB ports. It serves as the definitive choice for precision analog instrumentation, automated data acquisition hubs, high-fidelity audio equipment, and secondary operational amplifier biasing grids.
Key Features
Symmetrical Dual-Rail Output: Generates high-precision positive 12V DC and negative 12V DC power lines at the exact same time from one single, low-voltage positive source.
Wide Input Voltage Compatibility: Functions flawlessly on input rails from 2.8V up to 5.5V DC, making it plug-and-play compatible with 3.3V logic lines, 5V USB ports, and single-cell lithium batteries.
Advanced Multi-Channel Switching Grid: Utilizes a high-frequency internal switching topology combined with low-resistance internal inductors to dynamically balance power delivery across both rails while minimizing electrical noise.
Miniature Space-Saving Architecture: Packs a complete dual-rail boost-buck transformation system into an ultra-small circuit footprint, allowing it to fit into tight sensor housings and crowded laboratory prototype grids.
Low Ripple Analog Optimization: Integrated with high-capacity smoothing filters to drastically reduce output ripple and high-frequency switching noise, preserving the signal integrity of sensitive analog probes.
Standardized 2.54mm Pin Out layout: The interface pins align perfectly with standard breadboards and prototyping jumper wires, ensuring quick and secure connections to your central systems.

Hardware Wiring & Interface Pinout
The module breaks out a highly organized, clearly labeled 5-pin interface that connects directly to your batteries, microcontrollers, and operational amplifier grids:
VIN (Power Input): Connects to your primary positive DC power source or battery rail (2.8V to 5.5V).
GND (Ground reference): Unified system common ground reference path that links your input supply, module tracking baseline, and analog circuit ground together.
+12V (Positive Output): Delivers the regulated positive 12V DC output rail straight to your target components.
-12V (Negative Output): Delivers the regulated negative 12V DC output rail straight to your target components.
EN (Enable Control Pin): Optional hardware toggle pin.
Floating/High (Default): The module is actively running and generating power.
Pulled Low (GND): Places the entire module into a low-power shutdown sleep state to save energy.
Common Applications
Operational Amplifier Biasing Arrays: Provide the balanced positive and negative dual-rail tracking lines required by analog operational amplifiers to process full alternative-current waveforms smoothly.
High-Precision Data Acquisition: Power advanced Analog-to-Digital Converters and Digital-to-Analog Converters inside commercial sensor interfaces, preventing measurement distortion.
High-Fidelity Audio Preamplifiers: Act as the steady, noise-filtered power core inside portable mixers, headphone amplifiers, and localized sound-processing nodes.
Industrial Sensor Instrumentation: Simultaneously power complex instrumentation transmitters, pressure transducers, and balanced medical logging arrays from a single mobile battery grid.
🛠️ Pro-Engineering Operating Tip: Because this is a low-power analog biasing module engineered for precision signal conditioning, it is optimized for high voltage stability rather than driving high-current heavy motors or solenoids. To maintain absolute symmetrical equilibrium between the positive 12V and negative 12V outputs, ensure that the continuous load current drawn by your circuit components remains under 40 to 50 mA on each rail.
