HelloLeonard
Interesting ....
First, the two power stages in the PMP6712 already share current in a master / slave arrangement. The error amplifier (COMP1) of U5 should be considered a current demand signal that the PWM logic within U5 will use as…

Hello,
I am looking for High-side NMOS Static Switch Driver. The NMOS FET is used as Ideal Diode for paralleling up to ten 600W PSFB…
Hi Salva,
thanks for your interest in UCC39002.
Unfortunately UCC39002 is an old part and at that time the designer do not creat the simulation module.
the aviable document is the calculator with both excel and mathcad version.
if you need the…
Thanks David. The load current is the same on the sense resistors.
They analyze the initial startup of the three bricks. We noticed that in the initial power up, the current sharing does not occur yet. One out of the three brick modules are always asked…
Generally speaking, you cannot connect two devices in parallel to increase output current. There is no mechanism to allow the two circuits to share the load equally. One will tend to go towards current limit, while the other will be at light load. You…
Hi Cao,
The UCC29002 compares the average per module current level to the output current of the respective module. If the average per module current, represented by the load share bus is higher than the module’s own output current, an error signal…
Hi,
The TI range of load share controllers are designed to work with lower voltages than the PFC bus, typically 5V to 12V range.
The following link, www.ti.com/.../technicaldocuments shows the existing set of reference designs.
The UCC29002 device…

I am designing multi output rugged power supply. Total power rating of this power supply will be 4.5 KW peak. I am exploring TI solution to…
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…
