The high efficiency operation of typically 74% for a 12 volt
output means efficient use of your system power.
Easy four terminal operation makes using the converter a
snap. Just plug it in and you are ready to solve those nasty
analog problems that arise when only 5 volt digital power is
available in your system.

General Information
A
The 1 Watt SIP series provides isolated semi-regulated
outputs of 5, 6.5, 7, 12, 14, 15, 17, and 24 VDC. The high
efficiency low noise push-pull design operates at 350 kHz
which reduces to a minimum your external filter requirements.
The converter is packaged in a non-conductive plastic case
and can be water washed after assembled to your main PC
board.
Applying The Input
Figure 1 shows the recommended input connections for the 1
Watt Output SIP series. This series is only protected for
momentary output short circuits to common so a fast acting
fuse is recommended to protect the input circuit. It should not
be omitted as it serves to prevent unlimited current from
flowing in the case of an overcurrent at the load.
Figure 1. 1 Watt SIP Series Typical Application
0.5 ohm over the frequency range of DC to 350 kHz. A 10µF
solid tantalum capacitor will satisfy the requirements for C1,
and should be within 2" of the converter.
C1 may not be required when the power source is less than
2" from the unit. The source impedance should be less than

Figure 2 shows a very low noise input circuit that may be used
with the converters. This circuit will reduce the input reflected
ripple current to less than 5 mA peak to peak. L1 should be
sized to handle the maximum DC current of your application.
C1 must be used if L1 is required in the circuit.

inductor L2 appropriately for the maximum expected load
current. All the ground connections must be as short as
possible back to the CMN pin. The filter should be placed as
close as possible to the converter, even if your load is at some
distance.
L1 = 5µH
C1 = 10µF
Figure 2.
This circuit will reduce the input reflected ripple current to less than
5 mA peak to peak. See the discussion in the text for selecting C1
and L1.
Applying The Output
Figure1showsthetypicaloutputconnectionfortheconverter.
C2 is required to filter the output. It must be 10µF minimum
and can be made up of from the bypass capacitors already
used in your application. Increasing C2 will lower the output
noise.

Operation With Light Loads
Figure 3.
This circuit can reduce the output noise to below 4mV P-P over a 20
MHz bw. Size L2 for the maximum expected load current. Place as
close as possible to the converter.
This converter uses a semi-regulated design. The output
voltage will vary as the load is changed, increasing as the load
is decreased. See the Output Voltage vs. Output Load curve.
Negative Outputs
Operation With Changing Input Voltage
A negative output voltage is obtained by connecting the
+Output pin to the low side of the load, and taking the negative
output from the CMN pin of the converter.
The output will change proportionally to a change in the input
voltage. The typical output voltage change is 1.2% per %
change in input voltage.
Low Noise Output Circuit
Grounding
The circuit shown in Figure 3 can be used to reduce the output
noise to below 4 mV p-p over a 20 MHz bandwidth. Size
The input and output sections are fully floating and isolated
from each other. They may be operated fully floating or with
a common connection between the input and output.

temperature rating of 85°C to get 68°C, which is the maximum
Temperature Derating
ambient operating temperature.
The 1 Watt Output SIP series can be operated up to a +85°C
casetemperature.Casetemperaturecanberoughlycalculated
from ambient by knowing that the case temperature rise is
approximately 58°C per package watt dissipated.
This example calculation is for an application with no extra
air flow for cooling. Extra cooling air will greatly effect the
maximum ambient temperature. Exact internal power loss
depends upon the efficiency, input voltage, and load in the
application.
For example: If a 5S12.080SIP is delivering 0.9 watts at 5V
input, at what ambient could it expect to run with no additional
cooling such as moving air?
The above example is a rough approximation to the
maximum ambient temperature. Because of the difficulty of
defining ambient temperature, these calculations should be
verified by actual measurement before committing to a
production design.
Efficiency is approximately 74% which leads to an input
power of 1.2 watts. The internal power loss is 1.2 - .9 = 0.30
watts. The case temperature rise will be 0.30W x 58°C/
W=17°C. This number is subtracted from the maximum case
