ROHM Releases a New Compact PFC + Flyback Control Reference Design for Power Supply Solutions

Santa Clara, CA and Kyoto, Japan, Aug. 21, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the release of its new reference design (REF67004), capable of controlling two commonly used power converter types in consumer and industrial power supply applications with a single MCU: critical conduction mode PFC (Power Factor Correction) and quasi-resonant flyback. This design is part of ROHM’s LogiCoA™ Power Supply Solution that leverages analog-digital hybrid control technology. It combines an analog-controlled power stage circuit featuring ROHM’s superior silicon MOSFETs and gate driver ICs with a digitally managed power supply circuit built around the low-power LogiCoA™ MCU.
