500W AC/DC Primary-Side Digital Controller for Interleaved PFC and Half-Wave LLC

The RRW11011 is a high‑performance AC/DC primary‑side digital controller that integrates an advanced interleaved boost power factor correction (PFC) controller and a half‑wave LLC (HWLLC) controller. The device is optimized to operate with the Renesas RRW30120 secondary‑side controller for secondary‑side regulation (SSR).

With its integrated interleaved boost PFC stage, the RRW11011 improves power factor, total harmonic distortion (THD), efficiency, and EMI performance. Intelligent digital two‑stage control further enhances efficiency, reduces EMI, and minimizes audible noise across operating conditions.
