POWER INTEGRATIONS LinkSwitch-XT Flyback AC/DC Converter, 4W, SMD-8

The POWER INTEGRATIONS LinkSwitch-XT Series AC/DC Converter is a highly efficient, isolated flyback power supply IC designed for compact and reliable offline power applications. It integrates a 700V power switch and controller into a single 8-pin surface-mount package, simplifying design and reducing component count.

This converter operates from a wide universal input range of 85VAC to 265VAC, making it suitable for global mains power supplies. With a maximum output power of 4W, it is ideal for low-power auxiliary supplies, smart home devices, and IoT applications where space and efficiency are critical.

Key Features & Specifications

• Topology: Flyback for isolated, cost-effective power conversion.
• Isolation: Provides reinforced isolation for safety and noise immunity.
• Integrated Power Switch: Features a robust 700V, 250µA rated switch for high reliability.
• High Switching Frequency: Operates at 132kHz, allowing for smaller transformer and filter components.
• Wide Temperature Range: Functions reliably in harsh environments from -40°C to +150°C.
• Compact SMD Package: The 8-pin surface-mount design (SMD-8) saves valuable PCB space.

Engineers will appreciate its design simplicity, which eliminates the need for secondary feedback components, leading to a lower bill of materials and improved system reliability. It is a cornerstone component for creating efficient, compact, and safe power supplies in a vast array of electronic equipment.
