Description
The iW9861 digital AC/DC controller integrates Renesas’ patented quasi-resonant (QR) valley mode switching technology along with both CCM and DCM operation to enable ultra-small, light-weight, low-cost, and easily portable power supplies for smartphones, tablets, and other portable products. The iW9861 supports USB Power Delivery 3.0 with PPS at output powers up to 63W. It pairs with Renesas’ iW760 secondary-side IC, which integrates fast charge protocol support, USB Type-C® control, and synchronous rectification FET control.
Using proprietary intelligent power-saving technology, the iW9861+iW760 chipset consumes less than 20mW no-load standby power, without the need for an active startup DFET, making it the lowest standby power solution with the lowest total BOM count for adapters and chargers.
The iW9861 further reduces the total power supply BOM count and system cost by integrating innovative gate driving and EMI reduction technologies, resulting in very low EMI power supplies using a minimum of external components. The iW9861’s adaptive QR mode also allows the use of smaller passive components.
