STCH03TR

Offline PWM controller for low standby adapters

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameSO-8

The STCH03 current-mode controller is designed for an offline quasi-resonant ZVS (zero-voltage-switching at switch turn-on) flyback converter.It combines a high-performance low-voltage PWM controller chip and a 650V HV start-up cell in the same package.Constant output voltage (CV) regulation loop...

Key features
  • Advanced power management for ultra-low standby power consumption (under 10 mW at 230 VAC)
  • Fully integrated primary side constant current output regulation (CC)
  • 650 V embedded HV start-up circuit with zero power consumption.
  • Quasi-resonant (QR) zero-voltage-switching (ZVS) operation
  • Accurate and adjustable output OVP with options auto-restart (STCH03) or latched (STCH03L) after fault
  • Output undervoltage protection (UVP) with auto-restart
  • Input voltage feedforward compensation for mains-independent CC regulation
  • Embedded thermal shutdown
  • Intelligent frequency jitter for EMI suppression
  • SO8 package
