Inverting DC-DC Converter Module with TPS63700, 3.3 V and 5 V Input to Regulated -12 V Negative Output
The 7Semi TPS63700 Inverting DC-DC Converter Module is a compact power conversion solution designed to generate a stable negative voltage rail from a standard 3.3 V or 5 V supply. Built around the Texas Instruments TPS63700 inverting DC-DC converter, the module efficiently converts a positive input voltage into a regulated -12 V output, eliminating the need for bulky transformer-based power supplies or complex dual-rail power circuits. Its high-efficiency switching architecture minimises power loss and heat generation while maintaining stable output performance.
Ideal for analog electronics, operational amplifiers, sensor interfaces, audio equipment, instrumentation, and mixed-signal systems, the module provides a reliable negative power supply for applications requiring bipolar voltages. Integrated soft-start, overcurrent protection, thermal protection, and short-circuit tolerance enhance system reliability, while the compact PCB design allows easy integration into embedded systems, portable electronics, and production-ready designs.
