The 7Semi UCC14130 Isolated DC-DC Converter Board is a compact power module built around the Texas Instruments UCC14130-Q1 isolated DC-DC converter IC. Designed to provide galvanically isolated power, it operates from a 10V to 18V DC input and delivers isolated 12V and 5V outputs with an output current rating of up to 120mA, making it suitable for gate-driver and industrial power applications.
The board features an integrated isolation transformer with over 3kV RMS isolation, helping reduce ground loops and electrical interference between input and output circuits. It incorporates spread-spectrum modulation for low electromagnetic emissions, soft-start functionality, and built-in undervoltage, overvoltage, short-circuit, power-limit, and thermal protection.
For convenient integration, the board includes screw terminals, a 2.54 mm-pitch connector interface, separate input (GNDP) and output (GNDS) grounds, and a PCB isolation slot. The converter is enabled by default and can be disabled by pulling the EN pin LOW, with a maximum EN input voltage of 5V.
The module is suitable for MOSFET, IGBT, SiC, and GaN gate-driver circuits, motor drives, industrial automation, inverters, EV power electronics, and other applications requiring compact isolated power supplies.
