reference designGAN3R2-100CBE | Demoboard NX-HB-GAN3R2-BSC

Overview

Topology	Half-Bridge Converter Nonisolated
Input voltage	60 V
Output 1	60 V
IC revision	A

Description

The NX-HB-GAN3R2-BSC half-bridge evaluation board provides the elements of a simple buck or boost converter. This enables the basic study of the switching characteristics and efficiency achievable with Nexperia’s 100V E-Mode GaN FETs. The circuit is configured for synchronous rectification, in either buck or boost mode. Selection jumpers allow the use of a single logic input or separate high / low level inputs. The voltage input and output can operate at up to 60 VDC, with a power output > 350 W.

Features

The GAN3R2-100CBE is a a general purpose 100 V, 3.2 mΩ Gallium Nitride (GaN) FET in a 15 bump Wafer Level Chip-Scale Package (WLCSP). It is a normally-off e-mode device offering superior performance.
Enhancement mode - normally-off power switch
Ultra high frequency switching capability
No body diode
Low gate charge, low output charge

Typical applications

Class D audio amplifiers, mobile phone, laptop, tablet
Fast battery charging, USB type-C chargers
LiDAR (non-automotive), Motor drives
High frequency DC-to-DC converters in 48 V systems, High power density and high efficiency power conversion, AC-to-DC converters, (secondary stage)
Datacom and telecom (AC-to-DC and DC-to-DC) converters
