Board description
iSSI30R12H
Infineon's coreless-transformer advanced solid-state isolator (iSSI)
About this document
This user guide describes the functionalities and key features of Infineon's coreless-transformer advanced
solid-state isolator.
Scope and purpose
The iSSI solid-state isolator evaluation board EVAL-iSSI30R12H features the coreless-transformer advanced
solid-state isolator, iSSI30R12H. This user guide covers the design revision 1.0 of this evaluation board.
iSSI30R12H is certified as per UL 1577 (planned) and reinforced isolation (IEC 60747-17, planned).
Intended audience
Engineers who want to learn how to use Infineon's iSSI solid-state isolator iSSI30R12H
•
Experienced design engineers who design circuits with photovoltaic isolators (PVI), IGBTs, and MOSFETs
•
MOSFET
Design engineers who develop solid-state relays
•
Evaluation board
The evaluation board EVAL-iSSI30R12H is designed based on environmental conditions described in this
document. It has been tested as described in this document, but not qualified regarding manufacturing,
lifetime, or over the full range of ambient operating conditions. The boards provided by Infineon are not
subject to full production tests.
Evaluation boards are not subject to the same procedures as regular products regarding returned material
analysis (RMA), process change notification (PCN), and product discontinuation (PD). Evaluation boards are
intended to be used under laboratory conditions and by trained specialists only.
Note:
The printed circuit board (PCB) and auxiliary circuits are NOT optimized for final customer design.
