The TOPSwitch-JX is a highly integrated monolithic off-line switcher IC designed for off-line power supplies. TOPSwitch-JX integrated circuits enable design of power supplies up to 244 W, while providing high effciency under all load conditions. TOPSwitch-JX also provides very good performance at low load and during standby (no-load) operation. The TOPSwitch-JX family allows the designer to easily meet effciency requirements for the latest energy-effciency standards. Innovative and proprietary features enable design of compact and cost effective switching power supplies while reducing overall design cycle time and system cost. The TOPSwitch-JX family also enables the design of power supplies with robust functionality and provides enhanced safety features such as output overvoltage protection, overload power limiting and hysteretic thermal protection.Application Note AN-47 TOPSwitch-JX Family Design Guide Introduction detection feature allows glitch free start-up and shutdown of the power supply during line sag or line surge conditions.
