I am using TPS61021 boost converter IC to increase input voltage from 1.2V to 3.3V. I have designed the boost converter from the application called TI WEBENCH.
Input Voltage: 1.2V
Output Voltage: 3.3V
Min current: 300mA
The PCB that I have designed, is measuring 3.3V, but the efficiency is pathetic. It is well below 25%. In the BOM, TI WEBENCH software recommends using 10UF 10V capacitor, but I am using 10uF 6.3V. I am not able to understand why efficiency is so low? Datasheet for Inductor.
Below in the tabular format I have written current values that I have measured from multimeter.
