Web simulator simplifies part selection & system design

The tool enables users to simulate MOSFET performance under a variety of voltage and temperature conditions, as well as analyse the behaviour of LDO regulators and load switch ICs. MOSFET switching waveforms can also be analysed in AC/DC and DC/DC converter applications using different topologies such as full-bridge, flyback and synchronous buck converters. Toshiba's simulator is comprised of three interactive elements: datasheet and application designer covering MOSFETs; and design note covering LDOs and load switches.

The interactive MOSFET datasheet allows designers to select from a list of parts and then analyse the selection based on customisable curve tracker and dynamic characteristics test circuits. The search can be refined by adjusting parameters such as package type, resistance and voltage range.

The interactive application designer allows users to select a MOSFET device for various topologies, based on specific requirements. The online simulation and analysis tools then allow its performance to be evaluated in the application. A summary is generated including a circuit schematic and bill of materials, which can be printed, saved and shared with colleagues. It can also be exported for use in other simulator environments.

Offering similar functionality for LDO regulators and load switch ICs, the interactive design note allows user to identify parts based on chosen parameters, create a circuit design with a single click, analyse this and generate a bill of materials together with a summary document for reporting.

The tool is cloud-based and, therefore, enables data and designs to be easily shared among design teams in multiple locations. For added flexibility, the simulator can be downloaded and used in offline mode.
