iW662 AC/DC Secondary-Side Synchronous Rectification and Rapid ChargeTM Interface Controller for Qualcomm® Quick Charge™ 3.0 1 Description The iW662 is an AC/DC secondary-side combo controller for Qualcomm® Quick ChargeTM 3.0 (QC3.0) which includes USB interface, secondary-to-primary communication and synchronous rectification functions in a single IC. The iW662 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 mobile device (MD). It can be used in Dialog’s primary-side controlled AC/ DC systems to achieve fast voltage transition, low noload power consumption, and fast dynamic load response. The iW662 uses Dialog’s proprietary XM-Comm secondary-to-primary digital communication technology. When paired with Dialog’s primary-side controller, the iW1790, the optocoupler can be completely eliminated in the system. The iW662 transmits all necessary information for rapid charge through the power transformer, including output voltage requests, output current limits, output voltage undershoot, output over-voltage, and fault and reset signals. The iW662 is also an advanced synchronous rectifier (SR) controller with an integrated MOSFET driver, enabling discontinuous mode flyback converters with high efficiency operation. The device works with an external power MOSFET to replace the main rectifying diode on the secondary of a flyback converter, improving efficiency by reducing secondaryside conduction losses. Dialog’s digital adaptive turn-off control technology minimizes turn-off deadtime, eliminating the need for an additional Schottky diode that is typically needed in parallel with the synchronous MOSFET in conventional synchronous rectifiers. The iW662 and iW1790 provide double-layer cable protection. On the secondary side, the iW662 incorporates Dialog’s proprietary D+/D- over-voltage protection to address VBUS D+/D- soft shorts. On the primary side, the iW1790 uses Dialog’s SmartDefender+TM advanced hiccup technology to reduce the average output power during soft shorts without latch. Qualcomm® Quick ChargeTM 3.0 is a product of Qualcomm Technologies, Inc. 2 Features xx Primary side (iW1790): SmartDefender+TM smart hiccup technology reduces average output power at fault conditions without latch ●● XM-Comm proprietary secondary-to-primary digital communication transmits all information for rapid charge without an optocoupler: output voltage requests, output current limits, output voltage undershoot, over-voltage protection, and other fault and reset signals ●● Adaptive OVP/UV detection for most VBUS levels ●● Backward compatible with QC2.0 and USB Battery Charging Specification Revision 1.2 (USB BC1.2) ●● Lossless MOSFET VDS sensing for SR timing control with digital adaptive turn-off control ●● Wide operating voltage range from 3V to 16V ●● Optimized 5V MOSFET gate driver ●● High-voltage drain sensing up to 100V with no additional external clamping circuits required ●● 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 (iW662): Proprietary D+/D- overvoltage protection (OVP) addresses VBUS D+/D-soft shorts Product Summary www.dialog-semiconductor.com ●● Programmable active fast discharge from a high voltage to 5V at MD unplug or from a high voltage level to a lower level upon request with built-in switch or external switch ●● Intelligent low power mode enables < 20mW no-load power consumption ●● Dual Over-Temperature Protection (OTP) via on-chip temperature sensing circuit and external NTC (10lead MSOP package only) ●● 10-lead MSOP and 8-Lead SOIC packages Rev. 0.6 Preliminary 1 of 8 30-Oct-2017 © 2017 Dialog Semiconductor iW662 AC/DC Secondary-Side Synchronous Rectification and Rapid ChargeTM Interface Controller for Qualcomm® Quick Charge™ 3.0 3 Applications ●● 18W/24W QC AC/DC adapters for smart phones, tablets, and other portable devices L + + + COUT N VOUT - R1 NTC VCC 8 GND 2 SD 3 VSENSE 4 GATE 7 SOURCE 6 ISENSE 5 CFG GND U1 iW662 (10-Lead MSOP) U1 iW1790 1 VBUS 1 DRAIN SD 10 2 DIS VIN 9 3 D- 4 SOURCE GND 7 5 D+ OUT 6 VCC 8 D- R2 D+ Figure 3.1 : iW662 (10-Lead MSOP) 18W/24W Typical Application Circuit for Multi-Level Output Voltage and Current (Using iW1790 as Primary-Side Controller.
