TPS65150: [TPS65150PWPR] Question on C15

Katsu Sugita

Part Number: TPS65150

Hi,

On D/S 33 page, TI recommended 22pF on C15. however, We would like to change to 8pF to be stable on compensation loop . Do you have any issue without compensation loop?

Thanks,

Hello,

My apologies for bit of a delay in the response. Value of C15 should be calculated using equation 20 in the datasheet in conjunction with table 1 in the datasheet which provides proper values for compensation components and feed forward zero cutoff frequency. If you have problem calculating C15 value, please provide R1 value in your design and the input supply voltage and I will be able to provide an appropriate C15 value.

Kind Regards,
Liaqat
