ISOW7744: Input Capacitance of DCDC

Hi Michael,

Thanks for reaching out.
The minimum decoupling capacitor combination that we recommend on VDD pin of ISOW7744 is "10µF + 0.01µF", as also stated in the datasheet under section "Layout Guidelines". We also suggest that an additional 1µF is also used to support better filtering and maintain a stable supply. You can also refer to the below application note for more details on the schematic and PCB layout guidelines, thanks.
