Part Number: LM27402 Tool/software: Here's a post you can use for the forum:
Hello everyone
I'm currently working with the LM27402 regulator, and I'm trying to calculate its total power consumption for my application. The input voltage (Vin) is…
Part Number: LM27402 Other Parts Discussed in Thread: CSD86350Q5D , LM27403EVM-POL600 , TPS53632 , LM27403 Tool/software: I am working on a POL module that can do 12V-1V (and other standard POL output voltages). I like the design in LM27403EVM-POL600 and…
Part Number: LM27402 Hi Team,
Here are several questions on LM27402.
1. during OVP, will the part enter into hiccup?
based on description, seems only loop will turn on LS and turn off HS , and negative current limit is enabled. but from block diagram…
Part Number: LM27402 I'm seeing my LM27402 circuit output voltage droop / hiccup at low temperature. We use this LM27402 circuit output 2.8V DC power to drive the Red channel of LED display module, the red channel maximum current is about 6A, all the…
Part Number: LM27402 Hi Team,
I have some LM27402 module on hand, which works well on 12V input and 5V output up to 20A.
Here is the module circuit.
I am trying to add a CV/CC function to limit the output within 0.6-5V, 0-10A.
Here is the new circuit…
Part Number: LM27402 Other Parts Discussed in Thread: TINA-TI , , TPS548A28 Hi Team,
I download the simulation model from webite and use Tina-TI to do simulation. But it report below issue . Also , I use webench to do simulation and still cannot work.

Part Number: LM27402 Hi, can you check if the RFADJ value in FSW parameter is correct?
I used the formular in chapter 8.1.8 (page 23): RFADJ=(100/((fsw/100)-1))-5
and got 4.52KOhm, 20KOhm and 82.72KOhm for the fsw: 1150, 500 and 214KHz.

Part Number: LM27402 Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
"I like to get important feedback related to the temperature rise as I asked. Without going a complex thermal models/simulations we want to see basic and 1st…
Part Number: LM27402 Hi,
Continuation of Startup hiccup with 12V to 1V @ 14A regulator desgin , We gone ahead did simulation and implemented the changes.
On some of the boards we are facing LM27402 device is getting damaged after few hours of working.…
