Part Number: SM72441 Tool/software: How is the maximum power point tracking implemented? In a PV string with bypass diodes, could it get stuck in a local maximum because of partial shadowing or will it perform something like random jumps or scans to prevent…
Part Number: SM72441 Other Parts Discussed in Thread: SM72442 , SM72445
Hi,
The SM72445 has adjustable PWM frequency but it's not obvious to me what the diffference is between the SM72441 and SM72442. Can you explain please?
Could you explain why…
Hi Jason,
I do not support the SM72441 directly and my impression of the part become vague, but I think you can just use the part for the boost mode. It is because the device operate in pure buck, or pure boost, or buck-boost depending on the input…
Other Parts Discussed in Thread: SM72441 , SM72442 having some difficulty with the documentation on the SM72441 -- can't figure out how to setup the resistance networks for A0, A2, A4, A6. Is there other documentation than in the data-sheet -- perhaps…
Other Parts Discussed in Thread: SM72441 I am ME control system student. I wanted to know that SM72441 is suitable if i use 120W solar panel? I am making prototype. In this one more DSP SM72296 is used. So in that case DC-DC converter is required or not…
Other Parts Discussed in Thread: SM72441 , SM72295 Hello , i am ME control system student and i am doing project based on DSP that is A DSP based mppt control of an PV array.
I found that SM72441 suits my to project work . I want to make prototype.…
Other Parts Discussed in Thread: SM72441 , SM72442 , SM72445 As a reminder for people using the SM7244x devices:
- Output voltage limit can be modified on SM72442 and SM72441 by changing the voltage on pin A0 while the IC is running WITHOUT resetting…
Hello Jason,
Thank you for your interests in The SM72442. If you don't use the panel mode, you should select SM72441. With the SM72442 when the VIN is close to Vout, the panel mode kicks in. If you delete the two FETs, there would be not power flow…
Hi Bryan,
Sorry for the delay as I have been on a business trip. Sorry for misunderstood your max power level question. Basically this is a bridge type structure. If driver is strong enough and if you can find the inductor, it can support 1kW or higher…
