UCC28810EVM-003: LED driver

Part Number: UCC28810EVM-003
Other Parts Discussed in Thread: UCC25600

We are working on LED driver for that we are going to use  UCC28810EVM-003 110-W Multiple String LED Drive... Please give the solution of below questions.

1) Can we use UCC28810EVM circuit.

2) TPS92020D is not available. Could you please provide alternate part I did not get it. 

3) If we will not get the alternate part of TPS92020D... how will be the connection to the LED string.

  • Hi, You most certainly can use the UCC28810EVM circuit.  I suggest you order an EVM (which appear to be in stock) so you can work with it on the bench.

    UCC25600 is the same part with a different label, however, that appears to be out of stock at this time as well.

    TPS92023DR is a similar product which can be used and is in stock on a reel.  The switching frequency is increased from 300kHz to 330kHz and the burst function was removed to reduce flickering at light load.

    I hoped this helped.


  • Thanks,    ray
