LNK574 Overview
LinkZero-LP is an upgrade to the popular LinkSwitch-LP, the industry’s lowest ponent count charger/adapter and standby power switcher IC. The LinkZero-LP controller incorporates new technology which enables the device to automatically enter into and wake up from no-load mode while taking less than 5 mW from the AC power. IEC 62301 specifies measurements of standby power to a minimum accuracy of 10 mW, and so...
