(3)Diode Selection

Rectifier diode will affects efficiency greatly，Though a common diode (such as 1N4148) will work well for

light load，it will reduce about 5%~10% efficiency for heavy load，For optimum performance, a Schottky

diode (such as 1N5817、1N5819、1N5822) is recommended.

(4)Input Capacitor

If supply voltage is stable, the DC-DC circuit can output low ripple, low noise and stable voltage without

input capacitor. If voltage source is far away from DC-DC circuit, input capacitor value greater than 10uF

is recommended.
