LinkZero-AX LNK584: Zero Standby Consumption Integrated Off-Line Switcher
LinkZero-AX combines extremely low standby/power down energy use with the industry’s lowest component count standby supply solution. Below 3 mW at 230 VAC in power down (PD) mode meets IEC 62301 definition of zero power consumption and is immeasur-able on most power meters. LinkZero-AX is set into PD mode using an external signal to pull the FEEDBACK pin high for 2.5 ms. Such an external signal can be generated by a system micro controller or infrared controller. In PD mode the BYPASS pin remains regulated allowing the LinkZero-AX to be woken up with a reset pulse to pull the BYPASS pin below a reset threshold. Ultra low system consumption is therefore achieved without needing to disconnect the input voltage with a relay.
