Hi Serbat, sorr for the delayed response.
For UVLO external circuit, I recommend reading the following app note. This explains the design using UCC28180 but same principle applies for UCC28740.

I would like to try low power consumption comparator to replace LM2903 DR2G, your nice engineer…
Hi Robert,
Thank you for the quick reply.
For the brown in/out implementation, I would recommend the following circuit using LM8364 from one of the CCM PFC circuits.

Part Number: LM8364 Other Parts Discussed in Thread: TL431 , LM431 , TPS3701 Hello,
We are using LM8364 in a LED driver for AC line under voltage protection, we are trying to pull down the driver IC's supply pin with LM8364's reset pin.
But, we…
Part Number: LM8364 Other Parts Discussed in Thread: TPS3710 , TPS3847 Hi,
Our application requires a UVLO monitoring IC similar to LM8364 but with a wider input voltage range up to 12V or 14V. The threshold we are looking is around 2V.
And also it is mandatory…
Part Number: TPS3840 Other Parts Discussed in Thread: LM8364 Dear Team,
We suggested customer use TPS3840 to replace LM8364.
But The Vdd pin seems directly dedicated for its bias meanwhile as UV level. Can this pin be added to the resistor divider from…
Part Number: UCC28180 Other Parts Discussed in Thread: LM8364 , UCC28019A Hello Dear.
I'm using UCC28180D IC for PFC controller.
I would like to add the function of AC under voltage protection(Brown out).
I found the control IC LM8364 but the operating…
Part Number: UC3842 Other Parts Discussed in Thread: UCC24630 , LM2903 , LM8364 Hi Team,
Can I have some classical schematic suggestion for input under/over voltage protection based on UC3842? Tks a lot.

Part Number: UCC28911 Other Parts Discussed in Thread: LM8364
Dears:
Customer will evaluate UCC28911 and have some issue as below:
A. The precision of low voltage protection.
b. The precision of current-limiting protection.
c. The precision of constant…
Hi Deepak,
Thanks for your interest in LM5030. I would take a look at using a undervoltage sensing circuit like LM8364 to drive the SS pin. At the input, you can place a pulldown resistor which would trigger the undervoltage and the LM8364 will pull…
