Note:
1. All specifications are measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. The CTRL control pin voltage is referenced to GND.
In order to obtain better performance for the DC/DC
models.it’s recommended that use input and output
filters as Fig.1 shown.
3. Typical efficiency value at nominal input voltage and full load.
4. Capacitor MAX load tested at nominal input voltage and constant resistive load.
5. Refer to the diagram of Output Voltage trim up/down for trim applications.
6. The products cannot be used in parallel and in plug and play.

Requirement on output load
Output Graph
In order to ensure the product operate efficiently and reliably,in addition to a
max load(namely full load), a minimum 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 no less than 10% load.If the actual
load is less than the specified minimum load, the output ripple may increase
sharply while its efficiency and reliability will reduce greatly.If the actual
output power is very small,please add an appropriate resistor as extra
loading,or contact our company for other lower output power products.
