TMD2725 − ApplicationInformation
The dominant factor governing device performance is the
component placement, not necessarily component value. The
placement of the decoupling capacitor, C1, is the most critical.
Place the component on the same side of PCB as device as
shown in the figure above. Make connection as close as possible
to minimize series inductance and resistance. This is critical.
