STCH03 Offline PWM controller for low standby adapters Datasheet - production data SO8 Input voltage feedforward pensation for mains-independent CC regulation Embedded thermal shutdown Intelligent frequency jitter for EMI suppression SO8 package.
STCH03 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
