RY9420 provides different frequency and FB versions, which can be selected according to different 特 c applications. It offers a very pact solution to provide a 2A continuous output current over a wide input supply range, with excellent load and line regulation. ECOT PSM control operation provides very fast transient response r and easy loop design as well as very tight output regulation. The RY9420 requires a minimal number of readily available, external ponents and is available in a space saving 源 u SOT23-6 package.
