APPLICATION NOTE
①、NC is for internal use of the DC/DC converter. Be sure to suspend it without connecting any peripheral circuits.
②、By connecting a low ESR capacitor between this terminal and the pin-7 (connecting to the anode of the capacitor), the output ripple and noise may be further improved.
③、 When the output power is down to 1W, it is suggested to connect a capacitor(Cs) between the CS and the 0V. Generally, the capacitance is no greater than 100uF (see Figure 1).
④、 When the output power is down to 1W, it is suggested to connect a capacitor(Cs) between the CS and the 0V, otherwise perpetual damage might be done.(See T able 1)

⑤、 Recommended Circuit
All DC/DC converters of this series have been tested. This product cannot be tested with no load. Be careful n ot to perform the test under no load!!!For further reducing the ripple, increase the capacitance of the output capacitor
(C out) appropriately (see Table 2).
⑥、 Input Current
Nominal input voltage range. The input current of the power supply must be sufficient to the startup current (Ip) of the DC/DC module (see Figure 2)
⑦、Output Load
In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full load), a min load is specified for this kind of DC/DC converter. Make sure the specified range of input voltage is not exceeded, the minimum output load n o less than 25% (namely: ≥100mA) full load, the product never work under no load!If the actual load is less than the specified min load, the output ripple will increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, a proper resistor is needed at the output end in order to increasing the load, or contact our

Note
To get more ideal ripple value under high/low temperatures, please select a low-ESR tantalum
capacitor with a wider range of operating temperature or an OS-CON capacitor.
