Overview

JW1551 is an active clamp flyback controller for offline flyback converter applications. The JW1551 can be adopted to reduce switching loss and provide high efficiency in whole load range. JW1551 provide two control outputs, the main power switch control and the active clamp switch control. JW1551 also has X-cap discharge function to discharge the X-cap when the input is unplugged, which lowers standby power. The JW1551 is available in QFN4X4-20 package.
