Digital multiphase controllers and smart power stages for IoT infrastructure systems

Renesas Electronics Corporation now offers its 2nd generation of 15 new digital multiphase controllers, and six smart power stages supporting 10A up to 1000A+ digital computing loads for advanced CPUs, FPGAs, GPUs and AI ASICs benefiting IoT infrastructure systems. The ISL6822x, ISL6823x, RAA2282xx digital multiphase controllers and ISL993xx, RAA2213xx smart power stages expand the company’s digital multiphase platform to 41 devices. These solutions outpace the fast increasing power densities in data centre servers, storage, routers, switches, optical transport, as well as computing and 5G wireless infrastructure equipment.

“Renesas provides customers the industry’s widest digital multiphase portfolio and is the only supplier with 20-phase controllers for ultra-high current 1000A+ GPUs and AI ASICs,” said Andrew Cowell, vice president, Mobility, Infrastructure and IoT Power Business Division at Renesas. “Our customers appreciate the digital multiphase platform’s patented synthetic current control architecture for fastest transient response, reduced output capacitance and lower system cost. In addition, the digital multiphase controllers significantly reduce time to market with solder-free tuning of any application using Renesas’ PowerNavigator software, the first of its kind for digital multiphase controllers.”

The 15 new digital multiphase controllers are now available in 4mm x 4mm to 8mm x 8mm QFN packages.
