iW620 Product Summary Quick Charge 2.0 USB Adaptive Voltage Position Controller 1.0 Features 2.0 Description ●● Supports Qualcomm® Quick Charge 2.0 (QC2.0) High Voltage Dedicated Charging Port (HVDCP) Class A with voltage configuration of 5V, 9V, and 12V The iW620 is a Qualcomm® QC2.0 compatible USB adaptive voltage position controller for use in HVDCP AC/DC chargers/adapters. The device allows fast charging of QC2.0-enabled portable devices (PDs). The iW620 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 the 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 iW620 eliminates shunt regulator and loop compensation components at the secondary side and it has a built-in opto-coupler LED driver to minimize the bill of material cost. ●● Backward compatible with USB Battery Charging Specification Revision 1.2 (USB BC1.2) Dedicated Charging Port (DCP) ●● Programmable active fast discharge from 9V/12V to 5V at USB cable 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 <30mW 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 Dialog’s innovative proprietary technology ensures that power supplies designed with the iW620 and Dialog’s primary-side controller can achieve 5V/9V/12V output voltage configuration, low no-load power consumption with 5V output, and fast dynamic load response in typical quick charge AC/ DC charger/adapter designs. 3.0 Applications ●● Fast-charging AC/DC chargers/adapters for smart phones, tablets, and other portable devices L VOUT + + N RTN Configures 9V or 12V output U1 iW1760 NTC 1 VSENSE 2 SD 3 2 1 VCC DRV DIS GND 7 D- GND D+ 4 5 6 VCC 8 3 CFG OUTPUT 6 4 ASU ISENSE 5 + D+ RCDC D- OUT1 COMPARATOR U2 iW620 IN1+ IN1 OUT2 IN2+ IN2 Figure 3.1: iW620 Typical Application Circuit for 3-Level Output Voltage (Using iW1760 as Primary-Side Controller.
