OUTPUT POWER
The PWR40xxC series was designed to meet power requirements up
to 4W. Due to the nature of unregulated power supplies, a higher-than-
rated output voltage will result when less-than-rated power is used
(see Typical Performance Curves). This series has been designed to
run from no load to 4W without derating up to +70°C.
UNBALANCED LOADS
Unbalanced loads may be used on dual output models with each side
sourcing up to 200mA as long as the total power out is not more than
4W. With an unbalanced load, the output voltages will track within
5% of each other.
OUTPUT NOISE
The output noise can be reduced to less than 50mVp-p by adding a
low ESR 10μf tantalum capacitor across each output.

= +25°C, rated input voltage, rated output current unless otherwise noted.
APPLICATION NOTES
SHORT CIRCUIT PROTECTION
To maintain low cost, the PWR40xxC Series provides limited short-
circuit protection. To protect against continuous short circuits, a fuse is
required. It is recommended that the fuse be placed in series with the
input of the converter. The required I2 t will vary with input voltage.
