Power Integrations (San Jose, CA) has introduced new members of its LinkZero-AX integrated offline switching integrated circuit family, offering main power output up to 6.5 watts. LinkZero-AX eliminates wasted energy by employing a power-down mode that 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.
