LM2698: Compensation Values calculations

Part Number: LM2698
Other Parts Discussed in Thread: TLV61047

Tool/software:

Hi, 

I am designing Boost regulator using LM2698 with following specs

Vin = 5.2V
Vout = 11.6V
Iout = 0.4A
L = 10uH

Fsw = 1.2MHz

Power stage calculation 


Dominant Pole Freq : 248Hz

RHP zero Freq : 92KHz

ESR zero freq : 724KHz

  • My R and C compensation values are Rc = 40K and Cc= 1nF
    • which give compensation pole at 182 Hz and compensation zero at 4K.

Can you please confirm if my system will be stable with the calculated values ?

Regards,

Anurag Singh
