AC/DC Secondary-Side Controller for Qualcomm^®Quick

Charge^TM2.0 USB Interface and Secondary-Primary Communication

1 Description

The iW626 is an AC/DC secondary-side controller for QC2.0 USB interface and secondary-primary communication. The

device allows rapid charging of QC2.0-enabled PDs. The iW626 resides on the secondary side of an AC/DC power

supply and allows the adapter to be conﬁgured for 5V, 9V, or 12V output depending on the voltage requested by QC2.0

enabled PD. 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 iW626 implements Dialog’s proprietary secondary-

to-primary digital communication technique. When paired with Dialog’s primary-side controller iW1780, the iW626

eliminates the discrete decoders in the primary side and simpliﬁes system designs. The iW626 uses one opto-coupler

to transmit all necessary information for rapid charge, including output voltage requests, output current limits, output

voltage undershoot and output over-voltage. It also has a built-in opto-coupler LED driver to minimize the bill of material

cost.

Dialog’s innovative proprietary technology ensures that power supplies designed with the iW626 and iW1780

can provide 5V/9V/12V output voltage conﬁguration, with user-selected various output current limit combinations.

Furthermore, the chipset can achieve <10mW no-load power consumption at 5V2A output setting and fast dynamic load

response in typical AC/DC HVDCP adapter designs.

Qualcomm^®Quick Charge^TM2.0 is a product of Qualcomm Technologies, Inc.

2 Features

● Supports Qualcomm^®Quick Charge^TM2.0 (QC2.0)

technology High Voltage Dedicated Charging Port

(HVDCP) Class A with voltage conﬁguration of 5V, 9V,

and 12V

● Programmable active fast discharge from 9V/12V

to 5V at portable device (PD) unplug or from a high

voltage level to a lower level upon request with built-

in switch or external switch

● Normally OFF state with <120mA cut-off current

during 5V steady-state operation to achieve <10mW

power consumption at no load

● Proprietary secondary-to-primary digital

communication eliminates discrete decoders in the

primary side and simpliﬁes system designs

● Wide operating voltage range from 3V to 25V

● Single opto-coupler transmits all information for rapid

charge: output voltage requests, output current limits,

output voltage undershoot, and over-voltage protection

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

current of 2mA

● Backward compatible with USB Battery Charging

Speciﬁcation Revision 1.2 (USB BC1.2) Dedicated

Charging Port (DCP)

● 6-lead SOT-23 package

3 Applications

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

tablets, and other portable devices
