We are currently simulating a dcdc converter called the LTC3108.
The input voltage is 500mV and the output is 3.3V through the dcdc converter.
Here we have to calculate the efficiency of the circuit
efficiency = E_out / E_in = I_load * V_out / I_IN * V_IN
The load resistance and the capacitor were placed on the output side, and the output voltage and output current of the resistor were measured.
So, the calculation is that we need to know the voltage and the current. Now the simulation values are as follows.
So, you can see that efficiency calculation is strange ...
How do I calculate it?
E_out / E_in = (500mV * (-267.72mA)) / 3.3V * 33uA = -1225.
What is strange? I want get % value.
