Note:
1. All specifications measured at T
A
=25°C, humidity<75%, nominal input voltage and rated output
load unless otherwise specified.
2. When product begins to work, temperature may rise slowly until stabilize. It’s normal that output voltage
derating and efficiency reduce about 2 percent during this process.
3. Only typical model listed. If you need other model of this series (same power and package), please
confirm input and output voltage, then phone us.
4. No parallel connection or plug and play.
5. The CTRL pin voltage is referenced to GND.
6. If product has no use for CTRL pin, it’s name will change, add
“X”
in front of
“MP”
to distinguish.

APPLICATION NOTE
Recommended Circuit
All the URB_MP-12W Series have been tested
according to the following recommended testing
circuit before leaving factory. If you want to further
decrease the input ripple, Cin is recommended to use
100uF. If ripple and noise are required, you can
increase capacitance of Cout properly. However, the
capacitance
capacitance.
