Dear Analog Team,
I recently tested your evaluation board and I faced efficiency loss issue for low output voltage.
Please refer the evaluation board and test condition details below,
Evaluation Board: LTC3129 Demo Circuit 1922A.
Input Voltage: 2.4 to 4
Configured Output Voltage: 1.438V
Obtained Efficiency: 66.22%
Please refer below table for tested results,
As per datasheet graph efficiency would be greater than 80% but practically I couldn’t achieve it. Please refer below image,
What is the reason for efficiency loss? Could you clarify me?
