Given the physical layout of most systems, the current feedback (CSPx, CSNx) may have to pass near the
power chain. Clean current feedback is required for good load-line, current sharing, and current limiting
performance of the TPS51727. This requires the designer take the following precautions.
Make a Kelvin connection to the pads of the resistor or inductor used for current sensing. See Figure 33 for a
layout example.
Lay out the current feedback signals as a differential pair to the device.
Lay out the lines in a quiet layer. Isolate them from noisy signals by a voltage or ground plane.
Design the compensation capacitor for DCR sensing (C
SENSE) as close to the CS pins as possible.
Design R
PAR next to CSENSE.
Design any noise filtering capacitors directly under the TPS51727 and connect to the CS pins with the
shortest trace length possible.
The ISLEW pin is susceptible to high frequency noise. Design the trace lengths to the slew resistor as short
as possible and surround the pin and resistor with a guard ring of a quiet trace (analog ground is preferred).
Figure 33. Make Kelvin Connections to the Inductor for DCR Sensing
Ensure that all vias in the CSPx and CSNx traces are isolated from all other signals
Lay out the dotted signal traces in internal planes
If possible, change the name of the CSNx trace to prevent unintended connections to the V
OUT plane
Design CSPx and CSNx as a differential pair in a quiet layer
Design the capacittor as near to the device pins as possible
