This document is intended for the engineers involved in the evaluation, design, implementation, and validation of VR5500 high voltage PMIC with multiple SMPS and LDO. The scope of this document is to provide the user with information to evaluate the VR5500 high voltage PMIC with multiple SMPS and LDO. This document covers connecting the hardware, installing the software and tools, configuring the environment and using the kit. The KITVR55-FSSKTEVM enables development on VR5500 device. The kit can be connected to the FlexGUI software which allows you to play with registers, try OTP configurations, and burn the part. The device can be placed and removed easily from the board by using the socket. The device OTP can be burned three times, which provides a good flexibility. 2 Finding kit resources and information on the NXP website NXP Semiconductors provides online resources for this evaluation board and its supported device on
