Hello Robin,
Like many other SMPS designs using voltage-loop feedback, an ACF converter controlled by the UCC28780 cannot be directly paralleled with another without out some active or passive means to share current. The voltage loops of each converter…
Part Number: UCC39002 HI sir
I have a model with 54V/14.8A output and want to do load share
I tried to use the matchcad calculation provided by TI, but I found that the Radj_iadj data seems to be wrong
The following is the calculation data
Mathcad…
While I do not support LM5117-Q1 directly, I can make some comments.
Generally speaking, you cannot just tie the two outputs together. Usually the load currents will not be balanced. One converter will tend to run towards current limit. There are possible…
Hello Yusuke-San,
Colin has good feedback here. the only thing I would add-when using 2 UCC28950's in parallel as master and slave, you want to be sure you are using them both in peak current mode control, not voltage mode so that they balance the current…
Hello Well,
thanks for your interest in UCC39002.
since I am not familiar with the LDO controller, please help to confirm whether the LDO has such functions that must have when working with UCC39002.
1. The LDO should have romote sense capability…
Hello Don,
Thank you for such an excellent commendation for myself and for the UCC28070.
The advantages of the semi-bridgeless topology are that higher efficiency can be achieved and this can be significant at low line voltages.
Also there is no capacitor…
Part Number: UCC28950 Other Parts Discussed in Thread: PMP8740 Tool/software: Hello, can I get the design files of the charging module described in the article "Design Overview of a 2-kW Parallel-Connected Power Module"? Is there any other technical documentation…
Then what is the target power module for UCC29002?
There is no present target module which can be used with the UCC29002. The remote sense function is not compatable the UCC29002 requirements.
Tom
