Part Number: SM72445 Other Parts Discussed in Thread: SM72442 , Tool/software: SM72442 has a circuit in its demo board (SM3320) where there is a boost startup circuit for when battery voltage > panel voltage.
SM72445 on the other hand, does not have…
Part Number: SM72445 Other Parts Discussed in Thread: LM51770 Tool/software: I have been tasked with evaluating a SM72445 based 3,000W charge controller (3kW).
Output voltage is 48V nominal (52V max) and input ranges from 12 to 90VDC.
Maximum design…
Part Number: SM72445 Tool/software: My colleagues and I are performing a worst-case analysis for an aerospace application which involves Texas Instrument components as:
SM72445
We are interested to know more about temperature and/or ageing drift…
Part Number: SM72445 Dear Experts,
Do you see any problem not having the boost side of the output stage full bridge if I only want to use buck mode only?
Maybe on the boost drive signal I can put 100k pull-down resistors but apart from this I think…
Part Number: SM72445 Dear Team,
I am designing an MPPT converter for the specification of,
Pannel input voltage: 5V to 16.8V
MPPT output voltage: 16.8V@0.96A
I have found a solution from TI with SM72445 but, my end application is aerospace Low…
Part Number: SM72445 Dear Experts,
I would like to know how the SM72445 will know the exact input voltage if we put different resistor divider scaling on AVIN? Is it referenced to A0 scaling (Vout)? Because for the output voltage and current I understand…
Part Number: SM72445 Other Parts Discussed in Thread: UCC27712 Dear Experts,
I am designing a solar charger with SM72445 that charges 48V batteries. The input range of the solar cells varies from 30V to 180V so it means that
1:1 (100% duty cycle…
Part Number: SM72445 Other Parts Discussed in Thread: UCC27211 Hi all,
We are using the TI controller SM72445 for our DC/DC optimizer.
The MPPT function is working well, however, we have an issue on the dead-time of the control signals of the synchronous…
Part Number: SM72445 Other Parts Discussed in Thread: UCC27712 Dear TI,
I would like to make an MPPT design with SM72445 buck-boost controller.
My maximum input is 200V and the minimum is 20V. The output voltage would be between 50 and 60V. The…
Part Number: SM72445 Good day
I note the datasheet calls for a pull up resistor value of 60.4K to the 5V line. The Solar Magic design uses a 174K pull up resistor.
There is no explanation in the datasheet regarding the function of NC4 (pin 23) so…
