Schottky diode large than the output

voltage.

Capacitor Selection

Choose low ESR capacitors for the output

to minimize output voltage ripple. The

ceramic capacitor is a good choice for this

as well. A 4.7µF output capacitor is

sufficient for most applications. For

applications desire a smaller output

capacitance, a 2.2µF may be used. A 4.7µF

ceramic capacitor is recommended for the

input capacitance in the real system.

PCB Layout Consideration

Proper layout of the high frequency

switching path is critical to prevent from

noise and electromagnetic interference

problems. Due to high frequency switching,

the length and area of all the traces

connected to the switch node should be

minimized.
