From the shop's description

LNK3307D-TL 66kHz Offline Switcher IC Buck Boost Flyback SOIC-7 The LNK3307D-TL from Power Integrations is a highly efficient offline switcher IC that supports buck, boost, and flyback topologies. With a switching frequency of 66kHz and an integrated high-voltage MOSFET, this device simplifies the design of efficient and compact power supplies. It operates over a wide input voltage range and offers integrated protections such as over-voltage, over-temperature, and current limit. The LNK3307D-TL is ideal for power supplies and other applications requiring a flexible, high-efficiency, and cost-effective solution. It is housed in a small SOIC-7 package, making it suitable for space-constrained designs. This IC is well-suited for use in AC-DC converters, LED drivers, and other power management applications. Features: Supports buck, boost, and flyback topologies for flexible design options. Integrated high-voltage MOSFET for reduced component count. 66kHz switching frequency for efficient power conversion. Wide input voltage range from 85V AC to 265V AC. Built-in protection features: over-voltage, over-temperature, and current limit. Small SOIC-7 package ideal for space-constrained applications.
