LNK584DG-TL, AC/DC CONV, FLYBACK, 3W, 150DEG C

LinkZero™-AX combines extremely low standby/power-down energy use with the industry's lowest component count standby supply solution. Below 3mW at 230VAC in power-down (PD) mode meets IEC 62301 definition of zero power consumption and is immeasurable on most power meters. LinkZero-AX is set into power-down mode using an external signal to pull the FEEDBACK pin high for 2.5ms. Such an external signal can be generated by a system micro controller or infrared controller. In power-down 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 (1.5V). Ultra low system consumption is therefore achieved without needing to disconnect the input voltage with a relay. Typically used in ultra low consumption isolated or non-isolated standby and auxiliary supplies.
