About the Resonant converter PCB
Resonant converter is an open source PCB design by Dominik-Workshop, published on GitHub under the MIT license. It is a 4-layer board measuring 100 × 55 mm, with 115 components from 44 distinct parts.
Other key parts include the UCC256610DDBR, TEA2096T/1J, 78L15MG, PC817X2CSP9F and TL431AIDBVR. By type, the board carries 49 capacitors, 38 resistors, 10 diodes, 6 ICs, 6 connectors and 4 transistors.
From the project
Resonant converter PCB, 60V -> 12V 10A
This project is an LLC resonant converter. The power supply is designed to step down a nominal 60V input to a 12V output, capable of delivering up to 10A of continuous current (120W).
The board features power telemetry using an INA219 sensor, which can be easily interfaced via a standard QWIIC connector.
Input Voltage: 60V ± 5% Output: 12V @ 10A Topology: LLC Resonant Converter Telemetry: Onboard INA219 power monitor with a QWIIC I2C connector Magnetics:** Custom-wound transformer
