Part Number: TPS62092
The customer heard charge pump capacitor of TPS6209x is to have phase margin adjustment function. I don't think it correct but please let me confirm this.
Do we have a TPS6209x phase margin simulation data?
It's my pleasure to support you.
Quoting the datasheet at section 8.3.10:
"The CP and CN pins must attach to an external 10 nF capacitor to complete a charge pump for the gate driver. This capacitor must be rated for the input voltage. It is not recommended to connect any other circuits to the CP or CN pins."
So the phase margin is not affected by the charge pump capacitor.
I don't have simulation data of the phase margin, but I can provide you a measurement. What are the customer's Vout, Vin and load conditions?
Thanks and best regards,
