SLVS737 – FEBRUARY 2007
Connect the GND Pin of the device to the PowerPAD of the PCB and use this Pad as a star point. For each
converter use a common Power GND node and a different node for the Signal GND to minimize the effects of
ground noise. Connect these ground nodes together to the PowerPAD (star point) underneath the IC. Keep the
common path to the GND PIN, which returns the small signal components and the high current of the output
capacitors as short as possible to avoid ground noise. The output voltage sense lines (FB 1, ADJ2, DEF_1)
should be connected right to the output capacitor and routed away from noisy components and traces (e.g., SW
line). If the EasyScale interface is operated with high transmission rates, the MODE/DATA trace must be routed
away from the ADJ2 line to avoid capacitive coupling into the ADJ2 pin. A GND guard ring between the
MODE/DATA pin and ADJ2 pin avoids potential noise coupling.
