Semtech C-SIM is an interactive, web-based tool for selecting and simulating devices from our power management product portfolio. Based on the input and output parameters you choose, C-SIM will find suitable devices for your application. C-SIM allows you to capture schematics, create a reference design (along with associated Bill of Materials), view waveforms, perform application analysis and more.

Semtech C-Sim – Online Design Center for DC/DC Converters and LED Drivers

Design Requirements Interview

Simply enter your design requirements, such as input and output voltage and current, switching frequency etc.

Design Configuration

C-Sim automatically calculates optimum loop compensation and calculates appropriate values for inductors and capacitors.

Design Verification by Remote Simulation

Your design is displayed in an Online Schematic, which allows you to test your application in a virtual test bed. C-Sim allows AC, load, transient and steady state analysis.

BOM, Design, Summary Samples & More

Once the design has been verified, C-Sim generates a Bill of Materials and a comprehensive design report including simulation results, schematic and design data.

WebSIM® technology enables sophisticated online design and support solutions for semiconductor and other products. WebSIM covers a wide range of applications from power management, analog/mixed signal and electro-mechanical systems to Radio Frequency and Microwave and signal integrity applications.
