The IMS2 and IMS3 half-bridge daughter power boards are designed for users to gain hands-on experience
in the following ways:
•
Evaluate the GaN E-mode performance in any half-bridge based topology, over a range of
operating conditions. This can be done using either the accompanying power motherboard (P/N:
GS-EVB-HBDB-IMS) or with the users' own board for in-system prototyping.
•
Use as a thermal and electrical design reference of the GS66516B or GS66508B GaN
demanding high-power and high-efficiency applications.
