mosfet gate drive power calculator online

Use mosfet gate drive power estimate online for gate charge nC, drive V, frequency Hz. Average charge-delivery power; driver and gate dissipation partition excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter gate charge nC. Set drive V, frequency Hz. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
gate charge nCMain input. Positive values. 20
drive VOption. Positive values. 10
frequency HzOption. Positive values. 100000

Calculation method

drive_power_W = gate_charge_nC*1e-9*drive_V*frequency_Hz (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply mosfet gate drive power estimate to the case below, keeping the displayed units and assumptions. Average charge-delivery power; driver and gate dissipation partition excluded.

MOSFET Gate Drive Power Estimate — worked case

Settings: drive V: 10; frequency Hz: 100000

Input:

20

Calculated result for these inputs:

Output:

{
  "drive_power_W": 0.02
}

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Average charge-delivery power; driver and gate dissipation partition excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
