Key features
  • Input mains range: 190 to 264 VAC - frequency 50 Hz
  • Output voltage: 24 V 5%
  • No-load consumption: < 0.6 W
  • Efficiency @ 230 VAC > 92%
  • EMI: within EN55022 Class-B limits conducted pre-compliance
  • Safety: meets EN60950-1
  • Dimensions: 90 x 90 mm, 50 mm component maximum height
  • Safe startup procedure to avoid hard switching
  • Hard switching prevention in overload condition and low load condition
  • Burst mode in low load condition with smooth restart to prevent audible noise
  • Evaluation board can deliver more than 300 W peak power for a limited time by a thermal protection NTC positioned near output diodes
  • Continuous power at 30 °C ambient temperature:170 W
  • The power MOSFETs and diodes are both in D²PAK packages
  • RoHS compliant
