iW636
AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 3.0
USB Interface
1 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.
The iW636 implements Dialog’s proprietary secondary-to-primary digital communication technique. When paired with
Dialog’s primary-side iW1782 controller, the iW636 eliminates the discrete decoders on the primary side, simplifying
system designs. It uses one opto-coupler to transmit all the necessary information for rapid charging, including output
voltage requests, output current limits, output voltage undershoot, output over-voltage, and fault and reset signals. It
also has a built-in opto-coupler LED driver to minimize the bill of material cost.
The iW636 and iW1782 provide double-layer cable protection. On the secondary side, the iW636 incorporates Dialog’s
proprietary D+/D- over-voltage protection to address VBUS D+/D- soft shorts. On the primary side, the iW1782 uses
Dialog’s SmartDefenderTM advanced hiccup technology to reduce the average output power during soft shorts
without latch.
Dialog’s innovative, proprietary technology ensures that power supplies designed with the iW636 and iW1782
can provide multi-level output voltage configuration, with user-selected various output current limit combinations.
Additionally, the chipset can achieve <10mW no-load power consumption at 5V, 2A output setting and fast dynamic
load response in typical AC/DC rapid charge adapter designs.
2 Features

rapid charge: output voltage requests, output current
limits, output voltage undershoot (UV), over-voltage
protection (OVP), and fault and reset signals
●● Built-in opto-coupler LED driver with minimum driving
current of 2mA
●● 6-lead SOT-23 package
3 Applications
●● Rapid-charging AC/DC adapters for smart phones,
tablets, and other portable devices
