REFPDT006

Reference Design

A system-level evaluation board that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.

REFPDT006
Industry 48V, 400W Isolated DC/DC Converter with EcoGaN™ Reference Design

EcoGaN Logo

    Summary

    These are 48V isolated DC/DC converter reference design equipped with EcoGaN™, a next-generation device that is expected to greatly contribute to energy saving and miniaturization of equipments. Taking advantage of EcoGaN™'s device features, it is driven at high-speed switching frequencies (~500 kHz), resulting in smaller transformers and inductors and lower capacitance.

    Feature

    • Full-Bridge Isolated Step Down DC/DC Converter
    • High speed switching EcoGaN™
    • High speed Gate Driver for GaN HEMT
    • Isolated DC/DC Controller
    • Smaller components area compared with Si MOSFET based solution
