Applying the Output
The output is simply connected to your application circuit and
away you go. If extra low output noise is required in your
application the circuit shown in Figure 2 may be used to
reduce the output noise to below 10 mV peak-peak.
Grounding
The input and output sections are fully floating from each
other. They may be operated fully floating or with a common
ground. If the input and output sections are connected either
directly at the converter or at some remote location from the
Figure 2.
For very low noise applications the circuits shown above can be
used. The input current ripple will be reduced approximately 30 dB
of the original value while the output noise will be reduced to below
10 mV p-p. Do not use the biggest lowest ESR capacitors that you
can find in these circuits. These types of capacitors will cause
severe peaking in the filters transfer function and may actually make
the conducted noise worse.
converter it is suggested that a 1 to 10F, 0.5 to 5 Ohm ESR
capacitor bypass be used directly at the converter output pins.
This capacitor prevents any common mode switching currents
from showing up at the converters output as normal mode
output noise. Do not use the lowest ESR, biggest value
capacitor that you can find! This can only lead to reduced
system performance or oscillation. See our application note
“Understanding Output Impedance For Optimum Decoupling”
for more information.
Temperature Derating
The EC Single series can operate up to 100°C case
temperature without derating. Case temperature may be
roughly calculated from ambient by knowing that the 6 Watt
EC Singles case temperature rise is approximately 20°C per
package watt dissipated.
For example: If a 48 volt input converter was delivering 4
Watts, at 48 volts input at what ambient could it expect to run
with no moving air and no extra heatsinking?
Efficiency for a EC Single is approximately 78%. A little less
for some - a little more for others, check the product curves for
exact information. This leads to an input power of about 5
Watts. Therefore the case dissipation is 5 Watts (input power)
minus 4 Watts (output power) or 1 Watt. The case temperature
rise would be 1 Watt x 20°C/W = 20°C. This number is
subtracted from the maximum case temperature of 100°C to
get: 80°C.
This is a rough approximation to the maximum ambient
temperature. Because of the difficulty of defining ambient
temperature and the possibility that the loads dissipation may
actually increase the local ambient temperature significantly
or that convection cooling is suppressed by physical placement
of the module, these calculations should be verified by actual
measurement of operating temperature and your circuits
exact efficiency (efficiency depends on both line input and
load value) before committing to a production design.
