possible to the device. A 10µF input capacitor is sufficient
for most applications. Table 2 shows a list of several
ceramic capacitor manufacturers. Consult the manufac-
turers for detailed information in their entire selection of
ceramic parts.

PCB Layout Guidelines
The high speed operation of the LTC3426 demands careful
attention to board layout. You will not get advertised
performance with careless layout. Figure 2 shows the
recommended component placement. A large ground pin
copper area will help to lower the chip temperature.
Diode Selection
A Schottky diode is recommended for use with the LTC3426.
Use of a low forward voltage diode such as the ON
Semiconductor MBRA210LT3 is recommended. A Schot-
tky diode rated at 2A is recommended for use with the
LTC3426.
