iW1679-50
Overview
- Optimized for 5V2A AC/DC adapters/chargers with < 30mW no-load power consumption at 230VAC and fast dynamic load response for both one-time and repetitive load transients *
- Direct drive of low-cost BJT power switch *
- Very tight constant voltage and constant current regulation over entire operating range *
- PrimAccurateTM primary-side feedback eliminates opto-isolators and simplifies design *
- EZ-EMI® design enhances manufacturability *
- Intrinsically low common mode noise *
- Optimized 72kHz maximum PWM switching frequency achieves best size and efficiency *
- Adaptive multi-mode PWM/PFM control improves efficiency *
- Quasi-resonant operation for highest overall efficiency *
- Dynamic base current control *
