Infineon XMC Digital Power Explorer Kit, in distribution

May 04, 2016 // By Graham Prophet
This kit, which aims to provide engineers with easy entry into digital power control, features the XP baseboard – designed using RS’ DesignSpark PCB software – plus a pair of XMC microcontroller powered control boards.

RS Components positions the XMC Digital Power Explorer Kit from Infineon as being created for analogue power supply designers and embedded software programmers to help accelerate their learning in the capabilities of digital power control. The kit is also useful for digital engineers to gather a better understanding of PMBus technologies for the digital control of power supplies. It allows the easy and efficient development of almost any power topology combination including voltage, current or customised control.


The kit was developed in collaboration with Biricha Digital , (Reading, UK) which designed the buck converter board using the free-for-download DesignSpark PCB design software , and Würth Elektronik , which provided connectors and passive components including high-performance inductors and capacitors suited to digital power control applications. The XMC Digital Power Explorer Kit also features two Infineon ARM Cortex-M based XMC-microcontroller control cards, as well as Infineon’s DAVE v4 IDE software development platform for XMC microcontrollers, which is a free-of-charge code-generation system.


Ideal for applications such as industrial, telecom and server power conversion, the kit’s primary purpose is to help digital and power engineers bridge the technology gap to create digital power control solutions. Power system engineers increasingly need to explore the capabilities of the PMBusTM and incorporate basic digital-control techniques for modern power system design.


The kit main board includes a synchronous buck DC/DC converter with on-board resistive load banks, which can be switched between 10%, 55% and 100% of the maximum load to enable the testing of the transient response and the quality of the control loop under different load conditions, such as continuous-conduction versus discontinuous-conduction mode. Voltage-mode and peak-current-mode control with slope compensation are also available for the user to experiment.


The kit includes Infineon’s OptiMOSTM BSC0924NDI MOSFETs, and IRS2011S high- and low-side drivers. The control card options are an ARM Cortex-M0 based XMC1300 control card and an ARM Cortex-M4F XMC4200 control card with isolated on-board
