This tool simulate operation of the DC/DC converter,Provide design information for the selection of IC or peripheral components and circuit feasibility.
It can simulate characteristics such as junction temperature and switching frequency during PFM operation, which are difficult to calculate by common tools.

DC/DC Measured Electrical Characteristics Comparison Tool

  • Efficiency vs Iout
  • Ripple Voltage vs Iout
  • Total Mount Size vs Product
  • Vout vs Iout (Load Regulation)

Actual measurement data of DC/DC converter efficiency, ripple voltage, output voltage (load regulation), etc., and mounting area including peripheral components can be compared.
This is an ideal tool for selecting the IC best suited for the power supply specifications you are looking for, since you can easily compare the characteristics and mounting area of multiple products.

Power Consumption and Battery Life Calculation Tool for Actual Usage

Supply Voltage and Supply Current of MCU During Actual Use
Supply Current in Each IC
Example Circuits

This tool calculates the average power consumption and battery life of systems where the active mode or sleep mode transitions occur in MCU or similar devices.

In actual devices, the supply voltage and current consumption vary significantly depending on the operating mode, requiring complex calculations for estimating the overall system's power consumption. By using this tool, you can easily calculate the power consumption of the device and utilize it for accurate estimation of battery life and selecting the optimal power IC and peripheral components for the system.
