or the secondary side rectification of flyback. By driving an internal MOSFET, JW77198B is able to significantly improve the efficiency comparing with the conventional Diode rectifier. When JW77198B senses VDS of internal MOSFET less than -300mV, it turns on the internal MOSFET. Once the VSW is greater than -10mV, JW77198B turns off the internal MOSFET. JW77198B supports multiple operation modes, such as DCM, CrCM, CCM and Quasi-Resonant. By implementing the Joulwatt proprietary technology, JW77198B is able to handle CCM operation. JW77198B is available in SOP-8 package. Company’s Logo is Protected, “JW” and “JOULWATT” are
