RPT62-EVK001 User's Guide
The RPT62-EVK001 is a power tree solution reference board developed for infotainment devices such as vehicle clusters
and center information displays, as well as for ADAS ECUs. The power system that can support functional safety is
integrated on a single board, realizing an optimal configuration as a power tree. Good EMC performance that meets
CISPR25 Class 5 even when all power supplies are operating, and reduces heat generation of each device by distributing
high-efficiency DCDC. In addition, two voltage monitoring ICs with self-diagnosis functions can monitor the output of all
systems and contribute to a higher level of functional safety. This document provides an overview of the RPT62-EVK001
board, the names of each part, and how to use it.
