AC/DC Secondary-Side Controller for Qualcomm® Quick Charge^TM3.0

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 V_BUSD+/D- soft shorts. On the primary side, the iW1782 uses

Dialog’s SmartDefender^TMadvanced 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

● Built-in opto-coupler LED driver with minimum driving

current of 2mA

● Single opto-coupler transmits all information for

rapid charge: output voltage requests, output current

limits, output voltage undershoot (UV), over-voltage

protection (OVP), and fault and reset signals

● 6-lead SOT-23 package

3 Applications

● Rapid-charging AC/DC adapters for smart phones,

tablets, and other portable devices
