Design Resources

MPLAB® Analog Designer

Provides design suggestions for common circuit needs, estimates performance for common modifications, and can export to MPLAB® Mindi™ Analog Simulator for verification.

MPLAB® Mindi™ Analog Simulator

Uses a SIMetrix/SIMPLIS environment to model circuit behavior, reducing design time with software debugging for initial design verification.

Power Check Design Service

Provides advice on your exact physical circuit layout, sharing best practices from an experienced power supply designer, so that physical hardware will match simulations.
