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. （

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） www.belling.com.cn Ver1.0 6/ 14
