Hi support team,

how to calculate the value of R2 while UCC24612-1 in high side application

operation frequency 25K~65KHz

Vout = 12V/5A

Hi Red,

It is recommended to set the RC pole formed by R2 and C2 to be 1/100 of the maximum switching frequency. Using equation 6 in the UCC24612 datasheet and with C2=1uF, R2 should be 1/(2*pi*1uF*65kHz/100) = 244Ω or greater.

Best Regards,

Ben Lough
