LNK364 Low Power Offline Switcher IC SMD Package 

The LNK364 is a high-efficiency, low-power offline switcher IC from the Power Integrations LinkSwitch family, designed for compact and energy-efficient AC-DC power supplies. It integrates a high-voltage power MOSFET, control circuitry, oscillator, and protection features into a single device, greatly reducing component count and simplifying SMPS design.

The LNK364 is ideal for low-power switch-mode power supplies typically used in mobile chargers, standby power supplies, auxiliary power rails, IoT devices, and small adapters. It offers very low no-load power consumption and high efficiency, helping designs meet modern energy efficiency standards. The SMD package makes it suitable for compact designs and automated assembly.
