Broadcom GAN039-650NBB half bridge evaluation board
The H-bridge circuit is a full bridge DC-to-DC converter allowing operation of a brushed DC motor (48 V max, 12 V min, 5 A max). The control circuit operates with input voltages from 12 - 48 V for motors up to 250 W. The key feature of this design is that all electronic functions are designed with automotive qualified Nexperia discretes, MOSFETs and logic components (cost-effective, no microcontroller or software needed). In addition this H-bridge motor controller PCB allows the user to choose between three Nexperia MOSFET package options (LFPAK33, LFPAK56D or LFPAK56).
PCB view and efficiency
- The evaluation board uses 2nd generation 33 mΩ GaN FETs and are directly driven by the dual-channel ACFJ-3262 from Broadcom.
- Configurable in both buck and boost topologies
- Demonstrating 99% efficiency with hard-switching, utilising the Nexperia GaN FET GAN039-650NBB
- CCPAK GaN FET package technology delivers ultra-low inductance for lower switching losses and EMI
