LNK302 INTEGRATED CIRCUIT SOP-7

The LNK302 is a highly integrated offline switcher IC belonging to the LinkSwitch-TN family from Power Integrations. Encased in a compact SOP-7 (Small Outline Package with 7 pins), this IC is designed for low-power, non-isolated offline power supplies. It's a popular choice for applications requiring a simple, efficient, and cost-effective power conversion solution, such as appliance power supplies, LED drivers, and standby power supplies for consumer electronics. The LNK302 integrates a 700V power MOSFET, oscillator, simple on/off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a monolithic IC. This high level of integration minimizes the external component count, simplifying the design process and reducing the overall system cost. One of the key features of the LNK302 is its EcoSmart energy efficiency technology, which enables it to meet stringent energy efficiency standards, such as Energy Star and EuP directives.

This is achieved through its on/off control scheme, which optimizes the switching frequency based on the load conditions, reducing power consumption during light load or no-load operation. The LNK302 also incorporates frequency jittering, which reduces EMI (electromagnetic interference) emissions, simplifying the design of EMI filters and reducing the overall system cost. The LNK302 is designed to operate directly from a rectified AC input voltage, eliminating the need for a separate DC power supply. Its internal 700V power MOSFET provides a high level of voltage withstand capability, ensuring reliable operation in harsh environments. The LNK302 is easy to use and requires minimal external components. Its simple on/off control scheme eliminates the need for complex control circuitry, simplifying the design process and reducing the time to market.

The LNK302 is a versatile and reliable integrated circuit that offers a combination of high performance, energy efficiency, and cost-effectiveness. Its compact SOP-7 package, high level of integration, and simple control scheme make it an ideal choice for low-power offline power supplies.
