7Semi TPS63710 Low-Noise Synchronous Inverting Buck Converter Module, 6V-14V Input, -5V 1A Output
The 7Semi TPS63710 Negative Voltage Buck Converter Module is a compact, high-efficiency inverting DC-DC power supply built around the Texas Instruments TPS63710 synchronous inverting buck converter IC. It generates a stable -5V negative output rail from a positive DC input voltage ranging between 6V and 14V, making it a reliable solution for circuits that require a dual-supply or negative voltage reference. The module's synchronous rectification architecture reduces switching losses and output ripple, while its low-noise design ensures compatibility with noise-sensitive analog components such as operational amplifiers, precision ADCs, DACs, and sensor signal-conditioning circuits.
Measuring just 26mm x 9mm x 3mm, this module fits easily into space-constrained embedded and portable electronic designs. Three clearly labelled connections -- VIN, VOUT, and GND -- simplify integration with existing power trees or breadboard prototyping setups. Its continuous 1A output current capability and operating temperature range of -40 degrees C to +80 degrees C make it well-suited for industrial instrumentation, audio electronics, communication hardware, and laboratory power supply applications where a dependable, low-noise negative voltage rail is essential.
