Part Number: SM72441 Hi, Can I use it with just the 2 synchronous boost MOSFETs? There is no need in my application to buck the PV voltage (i.e. batt volts is always > PV volts) Second, I have an unusual requirement in that I need to be able to discharge…

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 Steven,
The maximum output voltage of SM72441 is set by A0 and use the following equation to calculate your Vout
RT1 to RT4 can be scaled to 20k ohms.
Use 2kohm for RFB2 where the value of RFB1 depends on your output voltage. You want to set the AVOUT…
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.
kindly…

- Output voltage limit can be modified on SM72442 and SM72441 by changing the voltage on pin A0 while the IC is running WITHOUT resetting the…
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…
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…
Sorry I cannot tell the distributor. I think you can prototype with SM72442 and change to SM72441 later.
Note that the PM_OUT pin of the latter is LED of the former. If you leave this pin open or grounded with a 10k, then you can simply replace…
