The iW1702 is a digital offline controller for AC/DC power supplies up to 45W optimized for 9V or greater output voltages. The part uses Dialog’s PrimAccurate™ primary-side control technology, eliminating the need for an optical isolation device on the secondary, reducing component count and cost.
For highest power density power supplies, the iW1702 can be paired with Dialog’s iW676 digital synchronous rectifier controller, which drives a power MOSFET on the secondary of the power supply to replace the main rectifying diode.
The iW1702 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 offers integrated active voltage position (AVP) control options that can be used for faster DLR while keeping the no-load power consumption < 75mW.
A full array of protection features are integrated, including SmartDefender™ advanced hiccup technology to protect against soft shorts in cables and connectors.
A DiaSIM™ simulation model (32-bit NL5 version only) is available for the iW1702. For more information and where to download, please visit the DiaSIM™ page.
