（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.

TEST CIRCUITS：

（

1） Output voltage test circuit（Iload=1mA）

（

2）Start-up voltage test circuit （Iload=1mA）

（3）Hold-on voltage test circuit（Iload=1mA）
