DERATINGS
PRECAUTIONS
Derating is necessary when ambient temperature exceeds 40°C or
50°C. Please refer to Table 1, DESIGN RECOMMENDATIONS.
• Series or parallel operation
Series or parallel operation of this product is not possible.

possible operation
A capacitor should be connected between the DC input termi-
nals (+) and (COM in). The capacitor of 100 to 330µF is appro-
priate, while the range depends upon impedance. For this
purpose, it should be used with a 0.3V/ms or higher incline of an
input voltage rise. A long rise time may disable the start-up.
• External capacitor
Ripple and noise can be reduced by connecting an external
capacitor to the output. Capacitance should be below the value
listed in the table 1, DESIGN RECOMMENDATIONS.
• Overcurrent protection

DESIGN RECOMMENDATIONS
Overcurrent protection is provided to protect the power supply
circuit from problems such as load short circuits, etc. It should
be noted, however, that 5 minutes or longer short circuit and a
use with overload are undesirable.
