SERIES DC/DC CONVERTER

C AND D TECHNOLOGIES 

TYPICAL PERFORMANCE CURVES

TA = +25°C, rated input voltage, rated output current unless otherwise noted.

APPLICATION NOTES

SHORT CIRCUIT PROTECTION

To maintain low cost, the PWR40XX 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.

OUTPUT POWER

The PWR40XX series was designed to meet power require-

ments 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.
