Part Number: UC3907 Other Parts Discussed in Thread: UCC39002
HI
requesting a circuit review for the UC3907.
When the output load current is 2.5A, when two SMPS are LOAD SHARE, each output current is measured as 1.35A, 1.15A.
How can reduce the two output…
Hi Andy
This level of current sharing at about 5% of full load is actually pretty good. Has the customer calculated what the typical imbalance should be ?
Offsets in the IC amplifiers can cause this level of imbalance. One of the main reasons for current…
Part Number: UCC29002 Other Parts Discussed in Thread: UC3907 , UCC39002 , TL431 Hi,
How can the UCC29002 get away without the 50mV voltage offset that is needed in uc3907 to stop the master trying to adjust its own reference?
Part Number: UC3845 Other Parts Discussed in Thread: UC3907 , , UCC29002 Hi,
we are designing a boost converter with 3kw output ,for modularity I break down the power requirement of 1500W each . in order to provide 3000w i am just paralleling the converter…
Other Parts Discussed in Thread: UC3907 I am using this load share controller and am looking to provide a status signal when the overall load exceeds a certain amount.
Hi all,
Is there any UC3907 Pspice model , I looked all over TI website and didn't find any , can I at least get the different parameters of the IC so i can build it on my if there's no model available.
looking forward to hearing from you. …
Other Parts Discussed in Thread: UC3907 We have two 24V duplicate DC supplies and are using the UC3907 on each to share the load between these two supplies. What we are finding is that the load is not equally shared. At some point one supply is allowed…
How calculate the values from voltage loop compensation between pin 12 and pin 11
what the voltage max generate by pin 9
can i use this controller with UC 3525 and how?
Thank you very much
Hello Kim Andy,
If you wish to use the UC2907 in an application that uses three power modules then each module must have the same power rating.
For example your total power is 200W so you will need three 70W modules.
And each of these modules will have…
Other Parts Discussed in Thread: UCC39002 , UC3907 , PMP10099 Hello,
I'm developing supply system that must have current equalization when paralleling units.
Searching for Texas chips, I read the data sheet and the app note for the UCC39002 (also for…
