USB PD EPR solution features Type-C port controller and buck-boost battery charger

Renesas Electronics Corporation has introduced the RAA489118 buck-boost battery charger and the RAA489400 USB Type-C port controller. The two new ICs combine to provide a premier EPR USB PD solution.

The company is a worldwide leader in USB-PD solutions, providing a comprehensive range of products, including turnkey solutions for various applications. It helps customers shorten their time-to-market with an extensive development environment and pre-certified USB-IF reference designs. The company's USB-PD solutions deliver superior quality, safety, high efficiency, and power density.

The RAA489118 functions as either a battery charger supporting two to seven battery cells in series or a voltage regulator supporting 30V input and 30V output. It employs the company's patented R3 (Robust Ripple Regulator) technology, which combines the best features of fixed-frequency and hysteretic PWM technologies. R3 modulation technology delivers acoustic noise-free operation, fast dynamic response, and best-in-class light-load efficiency for longer battery life.

The RAA489118 includes an SMBus interface widely employed in power tools, home appliances and light industrial products. The SMBus interface, combined with the buck-boost and bidirectional features, allows the device to work seamlessly with the RAA489400 and other components in USB-C PD implementations. Its input and output voltage levels also match mainstream solar power voltage levels, making it an excellent fit for solar portable power station applications.

The RAA489400 port controller supports USB-PD VBUS power up to 48V/5A. It features an integrated PHY, Sink and Source Power Path Gate Drivers with external NFETs, short-circuit protection, VBUS discharge, a VCONN MUX and dead battery support.

"Renesas has been a worldwide leader in battery charging for many years based on advanced technology, adaptability, and exceptional value," said Chris Allexandre, senior vice president and general manager of Power at Renesas. "The RAA489118 and RAA489400 bring those strengths along with Renesas' strong legacy of safety and reliability to new applications such as power tools and light industrial products. We expect to see strong demand from customers across multiple markets."
