IW662-00-SO8

Power Supply Controllers, Monitors Overview

The IW662-00-SO8 is an integrated secondary-side synchronous rectifier controller and rapid charge interface IC manufactured by Renesas Electronics Corporation. It utilizes XM-Comm technology to communicate with primary-side controllers, specifically the iW1790, iW1796, or iW1798, eliminating optocouplers in Qualcomm Quick Charge 3.0 and 2.0 solutions. The device features adaptive off-time control for synchronous rectification, reducing power loss during transitions. It operates within a temperature range of -40°C to +85°C and is housed in an 8-SOIC package with dimensions of 0.197 x 0.244 x 0.069 inches.

Power Supply Controllers, Monitors Feature Summary

• Integrates secondary-side synchronous rectifier control with rapid charge interface capabilities using XM-Comm technology.
• Enables optocoupler-less designs for Qualcomm Quick Charge protocols through communication with compatible primary-side controllers.
• Employs adaptive off-time control to minimize power loss during switching transitions without requiring parallel Schottky diodes.

Power Supply Controllers, Monitors Applications

• Qualcomm Quick Charge 3.0 travel adapters
• Qualcomm Quick Charge 2.0 travel adapters
• Low BOM cost AC/DC power supply designs

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (e.g., -00-SO8) against official Renesas documentation to confirm exact pinout and electrical characteristics, as variations exist within the iW662 family. Ensure compatibility with the intended primary-side controller, such as the iW1790 or iW1798, for proper XM-Comm protocol operation. Confirm moisture sensitivity level and lead-free status requirements for your assembly process.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing compact travel adapters that require support for Qualcomm Quick Charge 3.0 or 2.0 standards. It is suitable for applications prioritizing reduced bill of materials by removing optocouplers and parallel Schottky diodes. Ensure the design accommodates the SOIC-8 package constraints and operates within the specified thermal range for reliable performance in consumer electronics.

Power Supply Controllers, Monitors Part Context

The iW662 series belongs to Renesas' portfolio of power management integrated circuits designed for efficient AC/DC conversion. It complements primary-side controllers like the iW1790 to form complete chipset solutions for fast charging applications. This integration supports industry trends toward smaller form factors and higher efficiency in portable power delivery systems.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes are not explicitly listed in public data. Verify functional equivalence with other iW662 variants (e.g., IW662-05-SO8) only if datasheet parameters match exactly. Cross-reference with primary-side controller compatibility lists from Renesas before substitution.
