Explorer kit targets industrial, telecom and server DC-DC power conversion

Aimed at applications such as industrial, telecom and server DC-DC power conversion, Infineon XMC Digital Power Explorer Kit is now available from Mouser stock. An evaluation board for learning and testing digital power control applications, the XMC Digital Power Explorer Kit uses the XMC range of ARM Cortex-M microcontrollers, OptiMOS BSC0924NDI MOSFETs and IRS2011S high- and low-side drivers. The board features a synchronous buck converter that can be controlled digitally with XMC microcontrollers. The synchronous buck converter has on-board resistive load banks that can be switched between 10%, 55% and 100% of the maximum load. This allows the transient response and the quality of the control loop under different load conditions to be tested. For example continuous conduction mode vs. discontinuous conduction mode. The synchronous buck converter is one of the most well-known power topologies and many of the concepts of it can be ported to other power stages. This makes the synchronous buck converter a great platform for learning and experimenting. Two control card options are available (XMC1300, XMC4200) with an isolated on-board debugger that can be plugged in, to select between price/performance combinations. This board can implement voltage control and peak current control with slope compensation. Multiple test points are provided on the power board for checking the quality of all the relevant signals. Communication option via PMBus is provided for easy integration in more complex power management systems. This board is built with best-in-class Infineon Technologies components and with the collaboration of Biricha Digital and Würth Elektronik, says the company.
