Power Integrations introduced two new members of its LinkZero-AX product family (LNK585 and LNK586), along with a PI University introductory video course that explains how designers can achieve 0.00 watts of standby energy consumption. Launched in October 2010, the LinkZero-AX integrated offline switching IC family now offers increased main power output up to 6.5 watts — double the maximum output of earlier members of the product family. The expanded power range enables designers to utilize LinkZero-AX in a wider array of applications, including those with multiple auxiliary power functions, as is often the case in appliances, TVs, and remotely controlled electronic lighting ballasts. LinkZero-AX eliminates wasted energy by employing an innovative power-down mode that effectively turns off the auxiliary power supply when the application is idle, shutting down switch-mode operation and internal switch control circuits. LinkZero-AX can be re-awakened from power-down mode with a reset pulse or button press. Also, the bypass pin can provide up to 500 μA for use by any system-control or sensing circuit.
