1 of 7 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 confgured for 5v, 9v, or 12v output depending on the voltage requested by qc2.0 enabled pd. it can be used in dialogs primary-side controlled ac/dc systems to achieve fast voltage transition, low no-load power consumption and fast dynamic load response. the IW626 implements dialogs proprietary secondary- to-primary digital communication technique. when paired with di alogs primary-side controller iw1780, the IW626 eliminates the discrete decoders in the primary side and simpl ifes system designs. the IW626 uses one opto-coupler to transmit all necessary information for rapid charge, includ ing 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. dialogs innovative proprietary technology ensures that power supplies designed with the IW626 and iw1780 can provide 5v/9v/12v output voltage confguration, with user-se lected various output current limit combinations. furthermore, the chipset can achieve <10mw no-load power consum ption at 5v2a output setting and fast dynamic load response in typical ac/dc hvdcp adapter designs. qualcomm ? quick charge tm 2.0 is a product of qualcomm technologies, inc. 2 features supports qualcomm ? quick charge tm 2.0 (qc2.0) technology high voltage dedicated charging port (hvdcp) class a with voltage confguration of 5v, 9v, and 12v proprietary secondary-to-primary digital communication eliminates discrete decoders in the primary side and simplifes system designs single opto-coupler transmits all information for rapid charge: output voltage requests, output current limits, output voltage undershoot, and over-voltage protection backward compatible with usb battery charging specifcation revision 1.2 (usb bc1.2) dedicated charging port (dcp) 3 applications rapid-charging ac/dc adapters for smart phones, tablets, and other portable devices 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 <120 m a cut-off current during 5v steady-state operation to achieve <10mw power consumption at no load wide operating voltage range from 3v to 25v built-in opto-coupler led driver with minimum driving current of 2ma 6-lead sot-23 package IW626 ac/dc secondary-side controller for qualcomm ? quick charge tm 2.0 usb interface and secondary-primary communication rev. 0.6 preliminary product summary ? 2016 dialog semiconductor www.dialog-semiconductor.com 4-august-2016
