The LNK305DN - SMD is a highly efficient, low-cost off-line switcher designed to replace linear and capacitor-fed power supplies. This switcher operates over a universal input voltage range from 85V to 265V AC, delivering an output current of up to 175mA in discontinuous conduction mode (DCM) and 280mA in continuous conduction mode (CCM). Its integrated power MOSFET and oscillator, along with built-in protection features such as thermal shutdown and current limiting, ensure reliable performance in demanding applications.

The LNK305DN is ideal for use in appliances, LED drivers, and industrial controls, where low-component count and efficient power management are critical. It operates at a switching frequency of 66kHz, allowing the use of smaller, cost-effective external components. Its auto-restart feature provides protection during fault conditions, such as short circuits or open loops, while minimizing power dissipation. Packaged in a compact SO-8C form, the LNK305DN is designed for space-constrained applications, offering reliable performance with minimal energy loss.

Key Features :
  • Energy-Efficient Design: Designed for low-component count off-line switcher applications, providing efficient power management.
  • Universal Input Voltage: Operates over a wide input range from 85V to 265V AC, ensuring compatibility with global power standards.
  • 175mA Output Current: Delivers up to 175mA output current in discontinuous conduction mode (DCM) and 280mA in continuous conduction mode (CCM).
  • Integrated Protection Features: Includes thermal shutdown, overcurrent protection, and auto-restart during fault conditions, ensuring safe operation.
  • 66kHz Switching Frequency: Reduces external component size and cost while maintaining efficient energy conversion.
  • Compact SO-8C Package: Suitable for surface-mount designs with space constraints, offering easy integration into various systems.
