TPS56628: Boot Resistor to slow down leading edge ring

Antenna_Head

Part Number: TPS56628

Team-

Are there any concerns using a boot resistor in series with the boot capacitor to slow down the leading edge of the switching waveform of the TPS56628?

Any guidance on values?

Hi Dunbar,

Sorry for the late response. The boot resistor could be used for TPS56628. No specific rules for the value selection. You could try to use 1ohm first and then increase the value. You could refer to the app note: www.ti.com/.../slyt465.pdf

Best,
Anthony
