Key Features

  • Zero power consumption at no-load with lowest system cost (< 5 mW at 230 Vac with typical application circuit) *
  • Intelligent low power management achieves ultra-low operating current at no-load *
  • Adaptive load transient detection and fast response *
  • Very tight constant voltage and constant current regulation over entire operating range *
  • Primary-side feedback eliminates opto-isolators and simplifies design *
  • EZ-EMI ® design enhances manufacturability *
  • Intrinsically low common mode noise *
  • Optimized 72 kHz maximum PWM switching frequency achieves best size and efficiency *
  • Active start-up scheme enables fastest possible start-up *
  • Adaptive multi-mode PWM/PFM control improves efficiency *
