REF67004 - Reference Design
BCMPFC + QR Flyback Combination AC-DC Converter Topology
LogiCoA003-EVK-001 can supply 24V DC voltage with maximum 264V AC voltage input. And It can also supply up to 4A maximum. The MCU designed for LogiCoA™ technology, "ML62Q2035", can simultaneously operate BCMPFC and QR-Flyback topologies as the AC-DC power Reference design. The EVK can calibrate bootup voltage, shutdown voltage, over current threshold, and output DC voltage within several seconds and it can acquire various operation logs.
Reference Program
We offer a reference program comprising an OS for power control and firmware for REF67004 control. Additionally, we provide a communication GUI that allows communication from a Windows PC. Please utilize these as design references. Reference Program and Communication GUI (Excel file) are available here.
