Part Number: UCC27714 Other Parts Discussed in Thread: UCC27712 , , , UCC27712EVM-287 , UCC27212 Hello team,
Hope you are doing well. Please see below question from the customer:
I prototyped using the UC27714. For proof of concept, I used 2 of the…

Very good explanation, that makes sense. Now, can you provide the same explanation on the UCC27712 EVM-287? Page 9 of the user guide instructs to turn on the input power (0…
Hello CT,
Thank you for the interest in the UCC27714, I am supporting this device and will work to address your questions.
For the first question: one of the considerations is the gate drive power which you calculate using the Qg, total gate charge…
Hello Subash,
I am an application engineer supporting the UCC27714 and will strive to address your question.
To determine if the UCC27714 can support the 1MHz operation, the total gate charge of the MOSFET's is required since the losses driving the…
Hi Amal,
Thanks for the clarification.
From a gate driver perspective, I have couple of comments/suggestions:
-On U1 and U2, as a general guideline when using half bridge drivers, you want to size the bias capacitors to be at least 10x that of…
Hi Gangadhar,
For voltages higher than 100V bus, I would recommend using gate drivers rated for 600V bus. They are more tolerant of transients on the switch node connection (HS pin). Few of the recommended parts are UCC27710, UCC27712 & UCC27714.

Part Number: LM5106 Other Parts Discussed in Thread: LM5101A , UCC27712 , TPS28225 , TPS51604 , LM5101B , LM5102 Hi,
my customer is using LM5106 and the drive current is small. They need at least 2A drive current, so I propose LM5101A/B, but this part…
Hello,
I work with Mamadou supporting half bridge drivers, and I have some comments and suggestions.
It looks like the voltage level of the HO-HS output is declining during the output pulses and the HB-HS bias is declining. I see that there are 3…
