Part Number: TPS23753A

Will I currently use TPS23753A at 443MHZ where there will be -102db noise, what suggestions can be ruled out?

Hi Allan,

Sorry for the delay, from the above description, the switching frequency is 443MHz or did you mean kHz? Or do mean the EMI plot shows a spike at 443MHz and switching frequency is something else (sorry I cannot read the resistance on the FRS pin in the schematic)?
