Additional pc board pads are provided for an
optional input bypass capacitor (C1). A ca-
pacitor maybe necessary when using long
wires between the power supply and circuit
board, or for adding a tantalum capacitor to
minimize input voltage transients that may oc-
cur when the input is hot-switched. Also, pads
on the board backside are provided for adding
a small Schottky diode (D1) that can increase
efficiency slightly under some conditions. But
adding a diode defeats the output disconnect
and short circuit protection features.
When verifying output ripple, it is important to
use the scope probe connection as shown in
figure 2.
See the appropriate LTC3526L Data Sheet for addi-
tional information.
