LNK564PN AC-DC Offline Switcher IC

LNK564PN AC-DC Offline Switcher IC 

The LNK564PN is a high-efficiency, low-power AC-DC off-line switcher IC from the Power Integrations LinkSwitch family, designed to create compact, energy-efficient switch-mode power supplies. It integrates a high-voltage power MOSFET, controller, oscillator, and comprehensive protection features into a single device, significantly reducing external component count and simplifying SMPS design.

The LNK564PN is ideal for low to medium power AC-DC power supplies, such as mobile chargers, adapters, standby power supplies, appliance control boards, and auxiliary power rails. It provides excellent efficiency, very low no-load power consumption, and high reliability, helping designs meet modern energy efficiency standards.
