LNK625DG-TL Energy-Efficient Off-Line Switcher IC 100kHz SO-8C
The LNK625DG-TL, developed by Power Integrations, is a high-performance, energy-efficient offline AC-DC switcher IC belonging to the LinkSwitch®-CV family, designed for accurate primary-side constant-voltage (CV) control without requiring an optocoupler. Housed in a compact 7-pin SO-8C surface-mount package, it integrates a 725V high-voltage power MOSFET, enabling a wide universal AC input range of 85V to 265V and delivering up to 8W continuous power (13.5W peak) for low-to-medium power applications. Operating at a fixed 100kHz switching frequency with frequency jittering for EMI reduction, this RoHS-compliant device supports an industrial temperature range of –40°C to +150°C, making it ideal for cost-sensitive, compact, and reliable power supply designs.
This IC combines high integration, low power consumption, and robust protection.
● It features primary-side CV control eliminating the need for optocouplers and secondary feedback circuits, simplifying design and reducing BOM cost.
● 725V integrated MOSFET supports universal AC input and withstands high voltage surges.
● 100kHz fixed switching frequency with frequency jittering minimizes EMI emissions, easing compliance with regulatory standards.
● Ultra-low no-load standby current (typically <30mW) enhances energy efficiency for always-on devices.
● Comprehensive protection includes over-temperature protection (OTP), over-current protection (OCP), short-circuit protection, and open-loop protection, ensuring system reliability under fault conditions.
