iW1767 Description
iW1767 Product Brief Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller 1.0.
iW1767 Key Features
- Ultra-low no-load power consumption with lowest system cost (< 20mW 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,
- 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 79kHz maximum constant frequency PWM switching with quasi-resonant operation achieves best size, e
- User-configurable 5-level cable drop pensation provides design flexibility
- EZ-EMI® design enhances manufacturability
- Adaptive multi-mo
