Introduction

AI Translation

LinkSwitch is specifically designed to replace low power linear transformer/RCC chargers and adapters at equal or lower system cost with much higher performance and energy efficiency. LNK520 is equivalent to LNK500 but optimized for use with bias winding feedback and has improved switching characteristics for significantly reduced EMI. In addition, if bias and output windings are magnetically well coupled, output voltage load regulation can be improved. With efficiency of up to 75% and < 300 mW no - load consumption, a LinkSwitch solution can save the end user enough energy over a linear design to completely pay for the full power supply cost in less than one year. LinkSwitch integrates a 700 V power MOSFET, PWM control, high voltage start - up, current limit, and thermal shutdown circuitry, onto a monolithic IC.

Features

AI Translation
  • Lowest cost and component count, constant voltage (CV) or constant voltage/constant current (CV/CC) solutions Optimized for bias winding feedback
  • Up to 75% lighter power supply reduces shipping cost
  • Primary based CV/CC solution eliminates 10 to 20 secondary components for low system cost
  • Fully integrated auto - restart for short circuit and open loop fault protection – saves external component costs
  • 42 kHz operation with optimized switching characteristics for significantly reduced EMI
  • Universal input range allows worldwide operation
  • Up to 70% reduction in power dissipation – reduces enclosure size significantly
  • CV/CC output characteristic without secondary feedback
  • System level thermal and current limit protection
  • Meets all single point failure requirements with only one additional bias capacitor
  • Controlled current in CC region provides inherent soft - start
  • Optional opto feedback improves output voltage accuracy
  • Consumes < 300 mW at 265 VAC input with no load
  • Meets California Energy Commission (CEC), Energy Star, and EU requirements
  • No current sense resistors – maximizes efficiency
