µF 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.

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.

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.
