I would like to try low power consumption comparator to replace LM2903 DR2G, your nice engineer…
Hello Balakrishna,
For a Brown-In and Brown-Out (BI/BO) function to be added to the UCC28180, I suggest to follow the circuit shown at the bottom-right edge of Figure 1 (on page 5) in this EVM User Guide: https://www.ti.com/lit/pdf/sluub81 . It uses an LM8364…
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.

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…
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: 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…
