Overview

This single-phase boost converter operates over an input voltage range of 120 V - 350 V and provides a non-isolated output of 221 V / 0.87 A. Input voltages above 221 V are passed through to the output. With an efficiency of greater than 97%, component losses are reduced, which results in lowers operating temperatures and minimal heat sink requirements. 

Features
  • Full load efficiency of 97.8% minimizes component losses
  • Low-loss design lowers component operating temperatures (<60C, Vin = 150 V) which reduces heatsinking requirements
  • Low output ripple voltage of <0.5% reduces or eliminates additional external filtering
