Silanna launches 100W fast charger reference design
Production-ready AnyPort design combines ACF controllers, high power-density DC/DC converters and GaN power switch
Silanna Semiconductor has expanded its family of fast charger reference designs with the company’s first 100W multi-port offering.
Built around Silanna’s CO2 Smart Power AC/DC controllers and high-frequency DC/DC converters, the RD-16 integrates a front-end PFC converter stage and provides a high-power-density, production-ready solution for multi-port 100W USB-PD applications delivering currents up to 5A.
Silanna’s RD-16 is a GaN-based solution that the company says will simplify and speed charger development by providing everything an engineer needs to rapidly prototype and test a fully functional 100W 2C1A multi-port unit.
The design is based on the AnyPort architecture, which offers the flexibility to complete a charger design for a given power level prior to specifying and configuring the specific number and type of output ports. By allowing a single base charger design to be deployed across a variety of end products with different output configurations, AnyPort can significantly reduce the complexity of fast chargers and adapters with multiple Type-C and/or Type-A output ports.
The RD-16 brings together Silanna’s SZ1131 fully-integrated AC/DC active clamp flyback (ACF) controller and the company’s SZDL3105 and SZPL3102S high-voltage, high-efficiency integrated buck converters offering ratings of 100W and 65W respectively. End-to-end peak efficiency exceeds 92 percent and is relatively flat across the universal input voltage range (90 – 265Vac). Because the reference design exceeds conducted and radiated EMI requirements, it eliminates the need for pre-production validation and certification, speeding up the production cycle.
“Our aim is to provide designers with all the tools and support they need to rapidly develop high-efficiency, small form factor, low component counts fast chargers,” says Ahsan Zaman, Silanna Semiconductor’s, director of product marketing. “By combining our CO2 Smart Power family of advanced AC/DC and DC/DC technologies with GaN power switching and our innovative and flexible AnyPort architecture the RD-16 offers the fastest possible route from prototyping to full production for 100W fast chargers with any number or type of output ports.”
