Renesas Electronics RRW22121
The RRW2212x is a System-in-Package (SIP) product that integrates a 700V SuperGaN GaN FET with a high-performance AC/DC primary-side digital flyback controller for secondary-side regulation (SSR) operating with generic shunt regulator such as TL431 and other third party secondary-side controller for a broad range of end applications. The RRW2212x operates in Renesas’ patented constant-frequency, quasi-resonant (QR) switching mode and adaptive multi-mode control (MMC). The RRW2212x’s unique MMC mode of operation includes PWM, PFM and burst mode, which optimizes flyback converter performance including efficiency and EMI.
