The iW1830 is a high performance AC/DC power supply control device that uses digital control technology to build peak current mode PWM flyback power supplies. The device includes an internal power MOSFET and operates in quasi-resonant mode and includes key built-in protection features. This combination of features and integration simplifies design, improves efficiency, reduces EMI and lowers the bill of material cost
PrimAccurate™ primary-side feedback eliminates opto-isolators and simplifies design ? Integrated 700V power MOSFET ? Tight constant-voltage regulation across line and load range ? Proprietary optimized 79kHz maximum PWM switching frequency with quasi-resonant operation achieves best size, efficiency and common mode noise ? No-load power consumption < 50mW at 230VAC along with fast dynamic load response and short turn-on delay in typical 15W adapter applications
