Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
1.0 Features
- - No-load power consumption < 50m W at 230VAC along with fast dynamic load response and short turn-on delay in typical 20W and above adapter applications
- - Primary-side feedback eliminates opto-isolators and simplifies design
- - Adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330μF to 6,000μF) with output voltage up to 12V
- - Tight constant-voltage regulation across line and load range
- - Proprietary optimized 79k Hz maximum PWM switching frequency with quasi-resonant operation achieves best size, efficiency and mon mode noise
- - User-configurable 5-level cable drop pensation provides design flexibility
- - EZ-EMI® design enhances manufacturability
- - Adaptive multi-mode PWM/PFM control improves efficiency
- - No external loop pensation ponents required
- - Built-in single-point fault...
