Overview
The Dual Output DC-DC Boost Module is an essential tool for analog circuit design. While standard power supplies only provide a positive rail relative to ground, this high-efficiency converter generates both a Positive (+V) and a Negative (-V) output from a single DC source (like a 3.7V Li-ion battery or a 5V USB port). This is the standard way to provide “Symmetric Power” to Operational Amplifiers (Op-Amps) and high-fidelity audio equipment without needing complex dual-battery setups.
Key Features
Dual-Rail Output: Provides both positive and negative voltages simultaneously.
Wide Output Range: Supports various configurations including pm 5V, pm 12V, pm 15V, and up to pm 24V.
High Efficiency: Advanced switching technology ensures minimal heat generation and maximum battery life.
Compact Footprint: Small enough to be integrated into handheld test equipment or portable audio gear.
Low Ripple: Designed to provide clean power for sensitive analog measurements.
