Dialog Semiconductor Introduces First USB-PD Interface IC Optimized For Power Supplies

Dialog Semiconductor » iW656

New interface IC, the iW656, lowers external component count reducing size, simplifying designs and lowering costs

Dialog Semiconductor unveiled iW656, the market’s first state machine based USB Power Delivery (USB-PD) interface IC. The device allows designers to develop standards compliant, highly efficient designs that charge fast and deliver high power density for small form factor travel adapters. Supporting rapid charge applications in AC/DC adapters for smartphones, tablets and other portable computing devices, the iW656 is compatible with the latest USB Type-C™ standard.

Dialog Semiconductor - iW656

Designed specifically to meet consumer demands for today’s travel adapters, Dialog’s state machine-based controller allows for far simpler adapter designs compared to that of traditional microcontroller unit (MCU)-based solutions. While other solutions typically require many external components, the iW656 was designed to support smaller, more compact designs, requiring far fewer components, as well as leveraging the inherent lower costs and simplicity of state machine-based ICs. Applications can take full advantage of the power of USB-PD, a technology that can support higher power demands and faster charging for compatible devices compared to previous USB charging technologies.

The new USB-PD IC has been designed to pair seamlessly with Dialog’s market-leading AC/DC controller ICs, creating complete optimized Dialog adapter chipset solutions. The iW656 also supports other fast charge protocols, including Samsung Adaptive Fast Charge (AFC) and Qualcomm® Quick Charge™ 2.0.

The iW656 is packaged in a 12-pin TDFN package, measuring just 3 × 3 mm with samples available now through Avnet.
