Informations produit
Aperçu du produit
The STCH03 current-mode controller is designed for an offline quasi-resonant ZVS (zerovoltage-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. The device features a unique characteristic: it is capable of providing constant output current (CC) regulation using primary-sensing feedback. This eliminates the need for dedicated current reference IC, as well as the current sensor, still maintaining quite accurate output current regulation.
- 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
