iW1762 Description
iW1762 Product Brief Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller 1.0.
iW1762 Key Features
- Ultra-low no-load power consumption with lowest system cost (< 20mW at 230VAC in typical 20W and above power supplies)
- Primary-side feedback eliminates opto-isolators and simplifies design
- Intelligent low power management achieves ultra-low operating current (~300μA) at no-load
- Adaptive load transient detection and fast response
- Adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330μF to 6,
- Tight constant-voltage regulation across line and load range
- Proprietary optimized 79kHz maximum PWM switching frequency with quasi-resonant operation achieves best size, efficiency
- User-configurable 5-level cable drop pensation provides design flexibility
- EZ-EMI® design enhances manufacturability
- Adaptive multi-mo
