The Best Full bridge control IC

(1/2) > >>

Faringdon:
We need to do Full Bridge, 120W, Vin = 90VDC, 24Vout, FSW 100-200kHz we'll see.
We need overload protection.
Its best to just use a cheap, simple , 8pin, single output, current mode controller (one that has inbuilt overload protection) and add D Type, Buffers, Dual Analog switch and FET drivers…as attached..
But nobody does this.

There is no offTheShelf Full Bridge driver IC with  inBuilt Overload protection….the extra components here are cheaper than having a Full Bridge control IC with the added components to do overload protection.
So why is it not done? (I take many apart...nobody do this.)

analityk:
It is quite weird configuration. Why not use halfbridge or HB-LLC?
From the other side there are full bridge phase shift integrated controllers, it seems to be overdesigned but it will work.
UCC28950, LTC1922-1, HIP4081AIBZ-ND

I've used the LTC3722-1 quite successfully on several designs.

Well, the best I’ve used personally is the TMS320F28335 from Texas Instruments >:D

Yes, that one is very good. No need for all these external components.  :clap:
