LAYOUT GUIDELINES
The input capacitor, C
, must be placed close to the
LM3519. Placing C
close to the device will reduce the
metal trace resistance effect on input voltage ripple. Metal
trace connections for the C
capacitor can increase the
effective series resistance, which affects output voltage
ripple and efficiency. Trace connections to the inductor
should be short and wide to reduce power dissipation, in-
crease overall efficiency and reduce EMI radiation. The di-
ode, like the inductor, should have trace connections that are
short and wide to reduce power dissipation and increase
overall efficiency. For more details regarding layout guide-
lines for switching regulators, refer to Applications Note AN-
1149.
