JoulWatt Tech JW7726BLSOTB#TR

The JW7726BL is a synchronous rectification controller used for secondary-side rectification in isolated topologies, such as active clamp flyback and CCM/QR/DCM flyback. By driving an external MOSFET, the JW7726BL can significantly improve efficiency compared to traditional diode rectifiers. When the JW7726BL detects that the Vds of the MOSFET is less than -300mV, it turns on the MOSFET. Once the Vds is greater than -10mV, the JW7726BL turns off the MOSFET. The JW7726BL supports multiple operating modes, such as DCM, CrCM, CCM, and quasi-resonant. By adopting Joulwatt's proprietary technology, the JW7726BL can handle CCM operation. The JW7726BL comes in an SOT23-6 package.
