The JW4002 integrates a current mode boost converter followed by a tracking linear regulator. A high switching frequency is chosen to minimize the size of passive filtering ponents, further assisting in cost reduction. The tracking linear regulator protects the output against overload or short circuit. The JW4002 provides a number of Features described in Di SEq C. For Di SEq C munications, the 22 KHz tone signal can be generated from external clock, all the way down to no-load. JW4002 is available in ESOP8 packages. pany’s Logo is Protected, “JW ” and “JOULWATT” are Registered Trademarks of Joul Watt technology Inc. ESOP8 EXTM 14V19V Joul Watt Proprietary Information.
