Layout Considerations
Since the main voltage inputs to the TPS2363 are also the sense resistor inputs, some consideration must be
given to the layout for accurate read-back of the output currents.
Sense resistors are close to the TPS2363
TPS2363 pins SH12A/B and SH33A/B are not connected to inner layer power.
Connect the high side sense resistor to inner layer power.
Use a 0.1 mF to decouple the sense resistors close to the TPS2363.
Do not make additional connection SH12A to SH12B or SH33A to SH33B.
Depending on system conditions, it may be necessary to place a 1-nF capacitor either across the sense
resistor or from the low side of the sense resistor to ground close to the TPS2363.
