FAN53168
Signal Circuitry
• The output voltage is sensed and regulated between the
•
26
FB pin and the FBRTN pin (which connects to the signal
ground at the load). In order to avoid differential mode
noise pickup in the sensed signal, the loop area should be
small. Thus the FB and FBRTN traces should be routed
adjacent to each other atop the power ground plane back
to the controller.
