Reference Capacitor
Bypass REF with a 0.1F capacitor (C3). The REF out-
put can source up to 100A for external loads.
Layout Considerations
Proper PC board layout is essential to reduce noise
generated by high current levels and fast switching
waveforms. Minimize ground noise by connecting
GND, the input bypass capacitor ground lead, and the
output filter capacitor ground lead to a single point (star
ground configuration). Also minimize lead lengths to
reduce stray capacitance, trace resistance, and radiat-
ed noise. In particular, keep the traces connected to
FB and LX short. C2 must be placed as close as pos-
sible to the V+ and GND pins. If an external resistor
divider is used (Figure 3), the trace from FB to the resis-
tors must be extremely short.
