Description
General part information
IW1702 Series
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 Renesas' 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 theiW676digital synchronous rectifier controller, which drives a power MOSFET on the secondary side 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.
