iW1600

iW1600

10W AC/DC Digital Controller with <10mW Stand-by Power, Integrated Active Start0up Circuit and Fast DLR

A team of engineers is ready to answer your questions

Designed for high power density, compact, low BOM-cost off-line 10W power supplies 

The iW1600 PWM controller works with Dialog’s iW600 secondary-side voltage position controller for ultra-fast dynamic load response, while PrimAccurate™ primary-side control eliminates the need for an optocoupler.

The iW1600 directly drives a BJT for softer switching versus FETs, improving EMI and reducing the number of EMI filtering components.

With no-load power consumption of < 10mW, the iW1600 integrates an active start-up circuit for the shortest start-up time without sacrificing no-load power consumption.

Comprehensive protection features include SmartDefender™ advanced hiccup technology to help address soft short circuits in cables and connectors. Learn more about SmartDefender advanced hiccup technology here.
