Microchip’s digital power design suite includes the Digital Compensation Design Tool (DCDT), MPLAB®*VKL*VUњN\YH[VY4**4PJYVJOPW compensator libraries and design examples.

These four components of the digital power design suite provide the tools and required guidance for developing complete digital power designs. Once the initial simulation model of your design is ready, the DCDT can be used to analyze the design and the feedback transfer function, and to generate JVTWLUZH[VYJVLMњJPLU[Z+L]PJLPUP[PHSPaH[PVUJVKLJHUILNLULYH[LK^P[O[OL OLSWVM4**"HUK[OLњUHSњYT^HYLJHUILJYLH[LK^P[OZVTLOLSWMYVT[OL code examples and the code generated from MCC and the DCDT.
