Power Converter Efficiency Calculator

Analyze DC-DC converter efficiency. Break down losses and estimate junction temperature.

Input Voltage V_in (V)

Output Voltage V_out (V)

Output Current I_out (A)

Input Current I_in (A)

Quiescent Current I_q (mA)

Ambient Temp (°C)

Efficiency: η = P_out / P_in × 100%

Power Loss: P_loss = P_in – P_out

Junction Temp: T_j = T_a + P_loss × R_θJA
