Part Number:TIDA-00120
Hi,
I am using TIDA-00120 reference design for MPPT solar Charge controller.
As mentioned in the test results of TIDA-00120 i tried to upgrade the design to 48V system by changing the MOSFETs to 100V.
Changes made :
1. CSD18532Q5A is replaced with CSD19531Q5A
2. CSD18502Q5B is replaced with CSD19532Q5B.
After the above changes, we found the following.
At No load condition:
1. The output voltage is reaching to 35VDC when the input voltage is 45VDC.(Please look at attached waveform)
2. The output voltage is slowly decreasing to 0V when the input voltage reaches above 45.5VDC
Is there any changes required in the design or Source code? Please help
regards
