TPS23753A: Slope compensation

Part Number: TPS23753A

Hi,

I have a question about current slope compensation of TPS23753A.

If the slope compensation provided internally is enough,should I use 0 Ω for RS resistance?

When slope compensation is not enough,is there a possibility of causing oscillation?

Best regards,

Hi Seishin,

Yes, you can put zero resistor for Rs. But usually we put a 1kohms resistor here for more margin.

If the slope compensation is not enough, there may be a sub-harmonic oscillation.

Thank you.
