Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 , LM5155 , PMP23320 Tool/software: Hi team,
My customer has been considering the power requirement below, and BU team suggested LM5122-Q1 in multiphase configuration may be the best option…
Hello Kaji,
Thanks for using the e2e forum. Using the LM5122 as asynchronous controller is possible. For this case, SW pin should be shorted to GND, and BST pin should be connected to VCC. You can look at the IC pin connections of this reference design…
Hello Marco, thank you for using E2E. Yes it is possible to use LM51561, but it is more recommendable to use LM5122. You can have a look at this reference design PMP23320 reference design | TI.com

Part Number: LM5122 Other Parts Discussed in Thread: LM5156 , PMP23320 Tool/software: I am looking for a solution to implement a SEPIC with 200V output. The LM5122 looks like a promising option, and is even featured in the technical article in the following…
Hi Kaiji,
Thanks for using E2E!
As the power level is quite high, sync controller will be recommended on this.
You can refer to below reference design based on 2-phase LM5122, which is built in SEPIC topology to avoid the VOUT limitation. The Vout…
Hi Joseph,
Unfortunately, I did not find a reference design that does match your specs. The closest input/output parameter match was with a SEPIC design, where LM5122 is used asynchronous, meaning SW pin is connected GND and diodes are used instead…
