LinkZero-LP No-Load Consumption Off-Line Switcher Power Integrations LinkZero-LP Zero No-Load Consumption Integrated Off-Line Switcher is an upgrade to the LinkSwitch-LP, the industry's lowest component count charger/adapter and standby power switcher IC. It incorporates new technology, which enables the device to automatically enter into and wake up from no-load mode while taking less than 5mW from the AC power. Power Integrations LinkZero-LP Zero No-Load Consumption Integrated Off-Line Switcher comprises a 700V power MOSFET switch with a power supply controller on the same die. Unlike conventional PWM (pulse width modulation) controllers, it uses a simple ON/OFF control to regulate the output voltage.
