Renesas EBC10298 PSR GaN SIP Evaluation Board

Introduction

The Renesas EBC10298 is a power evaluation board designed to demonstrate an efficient isolated flyback power-supply solution. It combines primary-side regulation (PSR), gallium nitride (GaN) switching technology, and synchronous rectification to support compact AC/DC power designs up to 65 W.

Part Description

The EBC10298 PSR GaN SIP evaluation board is built around the RRW21111 PSR flyback converter for power levels from 25 W to 65 W, along with the iW673-20 synchronous rectifier controller. This combination enables a high-performance offline power architecture with reduced component count and improved conversion efficiency.

Key performance characteristics include:

• Supports power-supply designs from 25 W to 65 W
• Uses a PSR flyback topology for isolated power conversion
• Integrates GaN-based switching for efficient, compact designs
• Includes the iW673-20 synchronous rectifier controller
• Achieves greater than 94% efficiency
• Delivers less than 150 mW no-load power consumption
• Suitable for evaluating compact, energy-conscious AC/DC adapters and embedded power supplies

Applications

Potential applications for the EBC10298 include:

• USB-C power adapters
• Fast-charging wall chargers
• Notebook and laptop adapters
• Consumer electronics power supplies
• Smart-home device power systems
• Networked equipment adapters
• Industrial auxiliary power supplies
• Display and monitor power adapters
• Gaming-console and peripheral adapters
• Set-top box and media-device power supplies
