Preliminary Product Summary

iW9860

Zero Standby Power AC/DC Digital Quasi-Resonant Flyback Controller for RapidCharge^TMand Fixed Voltage Applications

The iW9860 is a high-performance AC/DC primary-side digital ﬂyback controller for secondary-side regulation

(SSR) that can enable zero standby power consumption in rapid charge and ﬁxed voltage applications to 140W.

The device operates in the Renesas’ patented constant-frequency, quasi-resonant (QR) switching mode and

adaptive multi-mode control (MMC). The iW9860 is optimized to work with multiple Renesas’ secondary-side

controllers such as the iW760, iW765 or iW690. These controllers integrate secondary-side regulation (SSR) and

synchronous rectiﬁcation (SR) control along with USB Power Delivery (PD) 3.0 with Programmable Power Sup-

ply (PPS) support and USB PD 3.1 support. A typical 25W USB PD travel adapter (TA) built with the iW9860 and

iW760 chipset can meet no-load power consumption of less than 5mW when the output USB cable is detached.

The iW9860’s unique MMC mode of operation includes PWM, PFM and burst mode, which optimizes ﬂyback

converter performance including eﬃciency and EMI. And it also provides a number of key built-in protection

features. The iW9860 and iW760/iW765 chipset can achieve tight multi-level constant voltage (CV) and multi-

level constant current (CC) regulation in high resolution steps, with fast and smooth CV/CC transition upon

request by mobile devices (MD). With SSR digital compensation, the chipset eliminates the need for external loop

compensation components while maintaining stability under all operation conditions.

Besides zero standby power, Renesas’ innovative proprietary technology ensures that power supplies designed

with the iW9860 and iW760/iW765 chipset can achieve high eﬃciency, high accuracy voltage/current control and

fast dynamic load response, all with the lowest system cost. And, power supplies designed using the iW9860

and the iW690 secondary-side IC can achieve zero standby power at output powers up to 140W in ﬁxed voltage

applications.
