iW600 Secondary-Side Voltage Positioning Controller 1 Description The iW600 is a secondary-side voltage position controller to detect the voltage undershoot. It can be used in Dialog’s primary-side control systems to achieve ultra-low no-load power consumption and fast dynamic load response. The iW600 operates in “Normally-OFF” mode with negligible power consumption during power supply normal steady state operation, while monitoring dynamic load change through the voltage on the secondary rectifier. A wake-up signal is transferred through the flyback power transformer to the primary side when a dynamic load change is detected. The iW600 eliminates loop compensation components and the optocoupler on the secondary side to minimize the bill of material cost. 2 Features ●● Fast system output voltage detection ●● No external components ●● Transmits detection signal to the primary side through flyback transformer ●● Enables
