Product details
Overview
The iW662-05-SO8 from Renesas Electronics is a secondary-side AC/DC combo controller integrating Qualcomm® Quick Charge™ 3.0 interface, XM-Comm digital communication, and synchronous rectification control in a single SOIC-8 IC. It enables multi-level VBUS output (3.6V–9V in 200mV steps), supports <20mW no-load power, and replaces optocouplers when paired with iW1790-08 primary controllers in smartphone adapter designs.
For engineers reviewing the iW662-05-SO8 datasheet, iW662-05-SO8 pinout, iW662-05-SO8 application, or iW662-05-SO8 equivalent, key selection considerations include its QC3.0 HVDCP compliance up to 9V, D+/D− over-voltage protection, lossless VDS sensing for SR timing, 100V drain voltage rating, and programmable fast discharge functionality.
Technical Context
The iW662-05-SO8 operates as a secondary-side controller in flyback converters, using XM-Comm to transmit voltage requests, current limits, OVP/UV signals, and fault resets across the transformer-eliminating optocouplers when used with iW1790-08. Its integrated MOSFET driver controls external SR FETs with digital adaptive turn-off to minimize deadtime.
It implements dual-layer cable protection: proprietary D+/D− OVP on the secondary side and coordinated fault response with the primary-side iW1790-08. The device supports backward compatibility with QC2.0 and USB BC1.2, and features an intelligent low-power mode enabling <20mW no-load consumption in optimized 18W/24W adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBUS Range | 3.6V to 9V in 200mV increments - enables QC3.0 rapid charge negotiation within restricted voltage envelope, excluding 12V support per customization note. |
| No-Load Power | <20mW - achieved via intelligent low-power mode and optimized gate drive, critical for Energy Star and EU CoC Tier 2 compliance. |
| DRAIN Voltage Rating | −1.5V to 100V - supports high-voltage flyback secondaries without external clamping, simplifying layout and reducing BOM count. |
| Gate Peak Current | ±3A - drives SR MOSFETs with fast edge rates, minimizing conduction losses during DCM operation. |
| ESD (D+/D−) | ±6,000V HBM - robust USB data line protection against electrostatic discharge in consumer charging environments. |
| Operating Voltage (VIN) | −0.3V to 33V - accommodates wide adapter output range and transient surges while powering internal LDO and sensing circuits. |
| OVP Threshold | Configured for nominal output - fixed per variant; iW662-05-SO8 uses iW1790-08 primary pairing with OVP tuned for ≤9V systems. |
Pinout & Package
Package: 8-Lead SOIC (SO8), surface-mount, standard footprint per Figure 4.1 in Rev. 1.3 Product Summary.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DRAIN | Analog input | Senses SR MOSFET drain voltage for lossless timing control; also serves as Pulse Linear Regulator (PLR) input for bias generation. |
| 2 - DIS | Analog output | Drives external fast-discharge circuit to safely collapse VBUS from high voltage (e.g., 9V) to 5V upon MD unplug or protocol request. |
| 3 - D− | Analog input | USB D− line interface for QC3.0 handshake and proprietary D+/D− over-voltage protection against soft shorts. |
| 4 - D+ | Analog input | USB D+ line interface; works with D− for bidirectional QC3.0 communication and integrated OVP detection. |
| 5 - OUT | Output | High-current gate driver output (±3A peak) for external synchronous rectifier MOSFET. |
| 6 - GND | Ground | Power and signal reference plane; must be low-impedance connection to minimize noise coupling into sensitive analog inputs. |
| 7 - VCC | Power input | LDO and PLR output; regulated at 5V when VIN > 5V; requires local decoupling capacitor for stability. |
| 8 - VIN | Analog input | Bias supply and output voltage sense node; connects directly to adapter VBUS for closed-loop regulation and UV/OV detection. |
Key Features
| Feature | Design Value |
|---|---|
| XM-Comm digital communication | Enables full rapid-charge signaling (voltage/current/fault) across transformer without optocoupler-reducing cost, size, and reliability risk in QC3.0 adapters. |
| Digital adaptive turn-off control | Minimizes SR MOSFET turn-off deadtime using real-time VDS sensing-eliminates need for parallel Schottky diode and improves light-load efficiency. |
| Proprietary D+/D− OVP | Protects against VBUS-to-data-line soft shorts on secondary side-prevents thermal runaway and ensures USB port safety without external components. |
| Programmable active fast discharge | Supports controlled VBUS collapse from high voltage to 5V on unplug or level change using built-in switch or external FET-meets USB PD and QC safety timing requirements. |
| Backward compatibility | Operates with QC2.0 HVDCP and USB BC1.2 protocols-enables single-platform adapter design supporting legacy and next-gen mobile devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secondary-side QC3.0 interface and synchronous rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| iW662-00-SO8 | Supports full 3.6V–12V VBUS range; uses iW1790-08/iW1796-08 primary pairing; higher kCC coefficient for 3.6V–8V range. | Required for full QC3.0 12V compliance; not suitable for iW662-05-SO8's 9V-limited designs. | Select iW662-00-SO8 only if 12V output and QC2.0 HVDCP compliance are mandatory; verify primary controller compatibility. |
| iW662-08-SO8 | Identical 3.6V–9V VBUS range and kCC = 0.422; paired with iW1796-08 instead of iW1790-08; supports <75mW no-load in 15W designs. | Optimized for lower-power adapters; uses different primary-side controller with distinct fault-handling behavior. | Choose iW662-08-SO8 when designing with iW1796-08-based platforms and prioritizing flexibility in primary-side architecture. |
Compared with iW662-00-SO8, the iW662-05-SO8 sacrifices 12V capability for tighter 9V compliance and simplified primary-side coordination with iW1790-08; versus iW662-08-SO8, it trades slightly higher no-load power margin for proven <20mW performance in 18W/24W applications using iW1790-08.

FAQ
What is the maximum VBUS output voltage supported by the iW662-05-SO8?
The iW662-05-SO8 supports a maximum VBUS output voltage of 9V, as confirmed in the Ordering Information table (Note 3). Unlike variants such as iW662-00-SO8, this part disables 12V operation to meet specific system-level compliance targets, and adapters using iW662-05-SO8 may not pass QC2.0 HVDCP testing due to the restricted voltage range.
Which primary-side controller is required for use with the iW662-05-SO8?
The iW662-05-SO8 is specified for use with the iW1790-08 primary-side controller, as documented in the Ordering Information table. This pairing enables XM-Comm communication, optocoupler elimination, and coordinated double-layer cable protection. Using iW662-05-SO8 with other primary controllers (e.g., iW1796) is not validated and may compromise rapid-charge functionality or safety features.
Does the iW662-05-SO8 support USB Battery Charging Specification Revision 1.2?
Yes, the iW662-05-SO8 is explicitly stated to be backward compatible with USB Battery Charging Specification Revision 1.2 (USB BC1.2) in Section 2 Features. This allows the iW662-05-SO8 to negotiate charging profiles with legacy non-QC devices while maintaining full QC3.0 functionality for supported smartphones and tablets.
How does the iW662-05-SO8 achieve <20mW no-load power consumption?
The iW662-05-SO8 achieves <20mW no-load power through an intelligent low-power mode that dynamically reduces internal bias current and gate drive activity during standby. This behavior is verified in the typical application circuit (Figure 3.1) using iW1790 as the primary controller, and is enabled by tight coordination between the iW662-05-SO8's DIS pin control and the primary-side burst-mode operation.
What protection features are integrated into the iW662-05-SO8 for USB data lines?
The iW662-05-SO8 integrates proprietary D+/D− over-voltage protection (OVP) to address VBUS-to-data-line soft shorts-a feature highlighted in both the Product Summary and Features sections. It provides ±6,000V HBM ESD protection on D+/D− pins per JEDEC JESD22-A114, ensuring robustness against electrostatic events in end-user charging scenarios.
