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 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 Earth Orbit…
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 I…
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) can…
Part Number: SM72442 Other Parts Discussed in Thread: SM72445 , Hello, The differences between SM72442 vs SM72445 is only switching frequency supported as follows?
SM72442: Switching frequency is only 220KHz SM72445: Switching frequency is 215KHz, 135KHz…
Part Number: SM72445
Hi, TI expert.
A customer company is developing it using 'SM72445', but in case of low power, an abnormal operation occurred and inquired.
The circuit is said to be configured the same as the EVM Board in the attached file…
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 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 it makes…
