AN2016-19 Application Note
Control Integrated POwer System (CIPOS™)
3-Phase Interleaved PFC IPM (IFCMxxU65yz) Reference Board
About this document
Scope and Purpose
The scope of this application note is to describe the product reference board of the CIPOS™ Mini 3-phase
interleaved PFC IPM and the basic requirements for operating the product in a recommended mode.
Environmental conditions were considered in the design of the reference board. The design was tested as
described in this document but not qualified regarding safety requirements or manufacturing and operation
over the whole operating temperature range or lifetime. The boards provided by Infineon are subject to
functional testing only.
Reference boards are not subject to the same procedures as regular products regarding Returned Material
Analysis (RMA), Process Change notification (PCN) and Product Discontinuation (PD). Reference boards are
intended to be used under laboratory conditions by specialists only.
Intended Audience
Power electronics engineers who want to evaluate the CIPOS™ Mini 3-phase interleaved PFC IPM.
