Fujitsu announces web-based design simulation tool ‘Easy DesignSim’ for power management ICs

‘Easy DesignSim’ helps engineers save time and money when developing power management ICs.

Fujitsu Semiconductor Europe (FSEU) has launched ‘Easy DesignSim’, a web-based design simulator for power management ICs (PMICs). ‘Easy DesignSim’ offers comprehensive online design simulation and support for design engineers working with Fujitsu’s extensive line of power management ICs, such as converters, switches, power supplies and charge control devices. This approach can significantly accelerate the development of consumer electronics and portable devices, as well as products for the medical electronics and office automation markets. The tool is the result of a collaborative venture between Fujitsu and Transim Technology Corporation.

“‘Easy DesignSim’ can save our customers a significant amount of time in the power management design process,” says Wolf Fronauer, Manager Marketing & Application, Business Unit Automotive & Embedded at Fujitsu Semiconductor Europe. “Engineers can use the simulator to validate or test their designs and power configurations right from the Fujitsu website. In line with our philosophy of delivering ‘right-sized’ solutions – and not merely hardware components – this new tool accelerates our customers’ time-to-market by keeping quality high while minimising design and test time.”

By simplifying circuit diagram design for power supplies, ‘Easy DesignSim’ offers engineers an effective way to select the right PMIC and substantially shorten the development process. The tool calculates key power parameters such as input/output voltages, load currents, efficiency and switching frequency automatically, and then simulates the operation of the power supply online. It’s then a simple matter for engineers to see how the simulation reacts in the generated circuit diagram when they change operating conditions and external component parameters.

After selecting a power management solution, engineers can use ‘Easy DesignSim’ to generate a bill of materials (BOM) matching the project requirements and circuit diagram from the databases of electronics parts vendors. The design engineer can then export the BOM as a Microsoft Excel or Adobe PDF file.


‘Easy DesignSim’ can be accessed from the Fujitsu website as of today. The tool initially provides simulation support for several of Fujitsu’s most popular PMICs, with more devices to be added. A comprehensive user guide gives step-by-step instructions for using ‘Easy DesignSim’.
