Power Integrations LNK304PN Environmental and export classification status description

of Power Integrations LNK304PN: The LNK304PN is an integrated circuit (IC) that functions as a switch-mode power supply (SMPS) controller. It is part of the LNK300 series, which is designed for low-power applications. The LNK304PN specifically targets compact designs with low standby power consumption and high efficiency. It is implemented in applications requiring low-power supplies up to 5W output. Functions: 1. Switching Regulator: The primary function is to control a switching power supply to provide regulated output voltage. 2. High Voltage Startup: Built-in high voltage switch allows the device to start up without external components. 3. Automatic Frequency Reduction: To enhance efficiency at low load, the device reduces switching frequency automatically. 4. Protection Features: Includes overvoltage protection (OVP), short-circuit protection (SCP), and thermal shutdown (TSD) to maintain safe operation. Applications: - Low power AC-DC power adapters and chargers for consumer electronics. - Small home appliances. - LED lighting drivers. - Standby power supplies for appliances and consumer devices. - Industrial applications requiring compact power supplies.
