Tool/software: Code Composer Studio
Hi,
I am trying to make a MPPT using the reference design of TI MPPT PMP7605 and using the same MPPT code provided by TI.
Regarding the issue, I have connected the MPPT with a power supply on the Panel side to provide voltage to MPPT. No load is connected and no battery is connected.
When I am providing voltage to the MPPT near 8V it takes 200mA current and settled down to 0 mA within a second but as I increase the voltage above 9V it takes a continuous 200mA current and one of the high side MOSFET (Q3) starts heating badly.
I have checked all the components and replaced MOSFETs and other ICs but still MOSFET Q3 is heating badly.
Can the 10uH inductor (L1,L2) be the reason for this ?
Can anyone please help me on this?
Best regards,
Nikhil
