< 30mW No-Load Power Using Adaptive Voltage Positioning Control IC (iW676)
The IW1602-00 is a digital offline AC/DC controller for up to 30W output travel adapters. It uses Dialog’s PrimAccurate™ primary-side control technology to eliminate the need for an optical isolation device on the secondary, reducing component count and cost.
The IW1602-00 integrates a unique light load operation mode that allows the user to configure the minimum switching frequency at light load through an external resistor. The higher the light load mode switching frequency, the better the dynamic load response (DLR). If the lowest switching frequency is chosen, the no-load power consumption is reduced, negatively impacting the DLR performance. In this case, the iW676 synchronous rectifier controller with integrated active voltage position (AVP) control can be used for faster DLR while keeping the no-load power consumption < 30mW.
The IW1602-00 integrates a full array of protection features, including Dialog’s SmartDefender™ advanced hiccup technology to protect against soft shorts in travel adapter cables and connectors. Learn more about SmartDefender smart hiccup technology here.
