Hi Team,

In UCC27712-Q1, Rgs (gate to source resistance) is said to be in the range 5k to 20 k. But exact design is not specified. Can you please specify the exact design ?

Thanks

Hi Avneet,

Thank you for reaching out! From the UCC27712-Q1 datasheet: "In the application example schematic there are 10-kΩ resistors across the gate and source terminals of FET Q1 and Q2. These resistors are placed across these nodes to ensure FETs Q1 and Q2 are not turned on if the UCC27712-Q1 is not in place or properly soldered to the circuit board or if UCC27712-Q1 is in an unbiased state."

These resistors can be tuned to help reduce gate ripple current in the circuit, but are not required. We have found that typical values for these resistors are between 5-kΩ and 20-kΩ, but the optimal resistance will depend on your circuit parameters.

Best,

Alex Weaver
