Description
General part information
iW1782 Series
The iW1782 is a high-performance AC/DC power supply controller for rapid charge that uses digital control technology to build peak current mode PWM flyback power supplies. The iW1782 is optimized to work with Renesas'iW636secondary-side controller for Qualcomm®Quick Charge™ 3.0 technology to achieve fast and smooth voltage transition upon request by mobile devices (MD). When paired with the iW636, the iW1782 eliminates the discrete decoders on the primary side, minimizes the external component count and simplifies system designs. The iW636 can communicate with the iW1782 through one optocoupler for all the necessary rapid charge information including output voltage requests, output current limits, output voltage undershoot, and output overvoltage.
The iW1782 also incorporates Renesas'SmartDefender™smart hiccup technology to address soft short circuits in charger cables and connectors helping to prevent excessive heat build-up and damage.
Qualcomm®Quick Charge™ is a product of Qualcomm Technologies, Inc.
