TPS54424: TPS54424 CBOOTについて

Akihisa Tamazaki

Part Number: TPS54424

Hello team，

My customer would like to use 0.1uF(0603mm size) because the customer cannot buy larger size chip capacitor. So the customer would like to use 2 pcs capacitors in parallel for CBOOT to consider DC performance of capasitor. Is it acceptable to use 2 pcs capacitors in parallel for CBOOT?

Hi Akihisa-san,

There is no problem with paralleling the capacitors to get enough capacitance from BOOT to SW. Make sure the capacitors used have at least 10 V rating and have X5R or better dielectric.
