Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK305P LNK305P

The LNK305P is part of the LinkSwitch-TN family of offline switchers designed for AC-DC conversion in applications requiring up to 175 mA output current. It operates at a frequency of 66 kHz and supports buck, buck-boost, and flyback topologies. The device features a high breakdown voltage of 700 V, providing robust input surge withstand capability. It includes integrated protection mechanisms such as auto-restart for short-circuit and open-loop conditions, which reduces the need for external components. The LNK305P is characterized by its energy efficiency, consuming typically only 50 mW in a self-powered buck configuration at 115 VAC input with no load. It meets various energy efficiency standards, including California Energy Commission (CEC) and Energy Star requirements. The device is suitable for applications such as appliances, timers, LED drivers, and industrial controls, making it a versatile choice for engineers looking for a cost-effective and reliable power supply solution.
