LAYOUT GUIDELINES

The input capacitor, C

must be placed close to the

LM3519. Placing C

metal trace resistance effect on input voltage ripple. Metal

trace connections for the C

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.
