iW1790

支持s Qualcomm® Quick Charge™ 3.0 and 2.0 without Optocoupler; Companion to the iW662 Rapid Charge™ and Synchronous Rectifier Controller IC

The iW1790 is a 27 W output, high performance AC/DCRapidCharge™power supply controller that integrates Dialog’sXM-Commtechnology, removing all optocouplers from travel adapters to reduce cost and improve reliability. The device also uses advanced source charging technology to integrate additional high voltage components, further reducing the overall BOM cost in travel adapter applications. The device supports Qualcomm Quick Charge 3.0 and 2.0 along with other rapid charging protocols.

优化它与对话框一起使用IW662.secondary-side device, which integrates a RapidChargeinterface IC and a synchronous rectifier controller. TheIW662.使用对话框XM-Commtechnology to transmit all necessary information to the iW1790, including voltage requests, output current limits, output voltage undershoot, output over-voltage, and fault and reset signals.

完整的保护功能包括对话框的SmartDefender™高级打嗝技术，可以在充电器电缆和连接器中寻址软短路，有助于防止过度的热积聚和损坏。
