General Description

The iW636 is an AC/DC secondary-side controller for USB interface supporting Qualcomm Quick Charge 3.0 (QC3.0) technology and secondary-to-primary communication protocol, to enable rapid charging of QC3.0/QC2.0-enabled mobile devices (MDs).

The iW636 resides on the secondary side of an AC/DC power supply and allows the adapter to be configured for multi-level output voltages from 3.6V to 12V in 200mV increments, depending on the voltage requested by the MD.

It can be used in Dialog’s primary-side controlled AC/ DC systems to achieve fast voltage transition, low no-load power consumption, and fast dynamic load response.

Overview

iW636 AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 3.

Key Features

  • Supports Qualcomm® Quick ChargeTM 3.0 technology High Voltage Dedicated Charging Port (HVDCP) to provide VBUS from 3.6V to 12V in 200mV increments.
  • Double-layer cable protection: xx Secondary side (iW636): Proprietary D+/D- overvoltage protection (OVP) addresses VBUS D+/Dsoft shorts xx Primary side (iW1782): SmartDefender™ smart hiccup technology reduces average output power at fault conditions without latch.
  • Proprietary secondary-to-primary digital communication eliminates discr.
