描述
Supports USB Power Delivery 3.0, Qualcomm® Quick Charge™ 3.0 and 2.0, and Direct Charge Adapters; Companion to the iW657P USB PD 3.0 Controller
The iW1791 is a 27W output, high-performance AC/DC RapidCharge™ power supply controller that supports USB Power Delivery (USB PD) 3.0 and other rapid charging protocols. The device uses advanced source charging technology to integrate additional high-voltage components and reduce the overall BOM cost in travel adapter applications.
It is optimized to work with Renesas' iW657P USB PD interface controller in mobile device adapters to achieve fast and smooth voltage transition on request from the mobile device. The iW657P accepts fast charging protocols, including USB PD 3.0. It transmits all necessary information via an optocoupler to the iW1791, including voltage requests, output current limits, output voltage undershoot, output overvoltage, and fault and reset signals.
A full array of protection features includes Renesas' SmartDefender+™ advanced hiccup technology to address soft short circuits in charger cables and connectors, helping to prevent excessive heat build-up and damage.
See the iW1781 for 45W USB PD 3.0 designs.
Qualcomm® Quick Charge™ is a product of Qualcomm Technologies, Inc.
