When designing circuits, especially power circuits, it's essential to choose a circuit configuration that aligns with the required specifications, as the input/output voltages, power levels, and isolation needs will vary by application. Optimal component selection also depends on the topology. Using inappropriate components can lead to performance shortfalls, potentially requiring a complete redesign of the circuit. ROHM’s topology selection page helps users identify the most suitable devices for various circuit designs.

ROHM provides a system-level evaluation board (solution board) that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.

ROHM offers simulation models, including thermal models, PLECS models, and Ray files, for circuit and thermal simulations of discretes and ICs, including power devices.
　
　

ROHM Solution Simulator is a new web-based electronic circuit simulation tool that can carry out a variety of simulations, from initial development that involves component selection and individual device verification to the system-level verification stage.

To ensure long-term reliability for industrial and other long-life equipment, we disclose supply periods for products covered under our Product Longevity Program.

On this catalog page, ROHM has compiled various brochures listing our products and solutions by market, application, solution, and product.

This white paper introduces ROHM’s comprehensive power solutions across power devices and analog ICs, with thermal design simulations, board-level design strategies, and real-world implementation examples.

This application note page compiles practical information for immediate use in design and evaluation, including how to interpret thermal resistance and heat dissipation, as well as key precautions for temperature measurement.
