SETTING OUTPUT VOLTAGE
To set the output voltage, select the values of R1 and R2
(see Figure 2) according to the following equation.

–
A good value for R2 is 13.3k which sets the current in the
resistor divider chain to 1.255V/13.3k = 94
μA.

LAYOUT HINTS
The high speed operation of the LT3467/LT3467A de-
mands careful attention to board layout. You will not get
advertised performance with careless layout. Figure 5A
shows the recommended component placement for the
ThinSOT package. Figure 5B shows the recommended
component placement for the DFN package. Note the
VIA’s under the exposed PAD. These should connect to a
local ground plane for better thermal performance.
