Performance/Functional Specications
Typical @ TA = +25°C under nominal line voltage and full-load conditions, unless noted.
Filtering and Noise Reduction
All TWR A-Series 12-15 Watt DC/DC Converters achieve their rated ripple
and noise specications without the use of external input/output capacitors.
In critical applications, input/output ripple and noise may be further reduced
by installing electrolytic capacitors across the input terminals and/or low-
ESR tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 5, 6
or 8) and Common (pin 7) as shown in Figure 2. The caps should be located
as close to the power converters as possible. Typical values are listed below.
In many applications, using values greater than those listed will yield better
results.
To Reduce Input Ripple
10μF, 100V
To Reduce Output Ripple
+5V Output
47μF, 10V, Low ESR
±12/15V Outputs
22μF, 20V, Low ESR
In critical, space-sensitive applications, Murata Power Solutions may be able
to tailor the internal input/output ltering of these units to meet your specic
requirements. Contact our Applications Engineering Group for additional
details.
These power converters require a minimum 10% loading on their primary output and a
minimum 20% loading on their auxiliary outputs to maintain specied regulation. Opera-
tion under no-load conditions will not damage these devices; however they may not meet
all listed specications.
Application-specic internal input/output ltering can be recommended and perhaps
added internally upon request. Contact Murato Power Solutions Applications Engineering
for details.
Devices can be screened or modied for higher guaranteed isolation voltages.
