Hi Kuan Wei,
You current is low, and Vout is high, so a non-sync boost controller can support your application. Because your input voltage can reach 54V, you may consider LM5020, LM5022, or the sync controller LM5122.
Regarding OVP, do you mean…
Other Parts Discussed in Thread: LM4041-N , LM431 Hi Team, My customer considers to use LM4041-N. Is there stability boundary conditions like the following LM431(datasheet page.5)? I believe LM4041-N is ensuring stability with any capacitive load so there…
Hi Hsu Cheng,
The TL431B is P2P with other shunt voltage reference devices such as the LM431, ATL431, TLV431, and TLVH431 but they will have different specifications. Are you looking for a direct P2P replacement for the TL431BCDVR?

Hi Jake,
Can you elaborate a little on what you need? If you are looking for a fixed voltage from a linear regulator to use as a reference, you can use one of the voltage references TI has available. You can see the portfolio at .
If you are looking…
Hello Steven,
I am moving this to the LED group that supports this part. I used to support this part in the past. The power supply portion is assumed to be an isolated DC output with a reference that can be connected to. It isn't covered as part of…
Other Parts Discussed in Thread: TL431 , LM431 Hello friends,
Currently I am using LM431A and TL431A for SMPS design for two different outputs.
Typically, 60V output feedback has LM431 and 24V output feedback has TL431.
I was goping through the…
Hello Vincent,
Let me try to help give a brief overview of the differences for your information.
The TL431 is the original standard shunt voltage reference.
The TLV431 is a lower voltage reference option of the TLV but also has some different specifications…
Add: The list shown in Figure 6 reads the reference circuit of the KCL equation as follow:
And the application report SNVA761A is attached. snva761a.pdf
LM3411 is specially designed for 3.3V and 5V output applications, with which the feedback circuit is greatly simplied. For regulation at your 500Vdc out, please consider a different device like LM431 with adjustable regulation setting.
By the way, the…
Other Parts Discussed in Thread: LM5088 , LM431 Helo, i am trying to build MPPT solar regulator with Lm5088 (input solar panel with Vpp~18V and output is 12V acumulator). I've tested Lm5088 alone, and it worked properly. Next i've modify feedback, with…
