iW1767
iW1767 is Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller manufactured by iWatt.
Features
- - Ultra-low no-load power consumption with lowest system cost (< 20m W at 230VAC in typical 12V2A power supplies)
- - Fast dynamic response with secondary-side load transient detection
- - 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 and constant-current regulation across line and load range with primary-side feedback and control
- - Intelligent low power management achieves ultra-low operating current (~250μA) at no-load
- - Proprietary optimized 79k Hz maximum constant frequency PWM switching 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...
