Qualcomm Quick Charge 3.0 Compatible Solution; companion to theiW636

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 Dialog’s iW636 secondary-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 opto-coupler for all the necessary rapid charge information including output voltage requests, output current limits, output voltage undershoot and output over-voltage.

The iW1782 also incorporates Dialog’sSmartDefender™smart hiccup technology to address soft short circuits in charger cables and connectors helping to prevent excessive heat build-up and damage. Learn more about SmartDefender smart hiccup technologyhere.
