Product Overview
The unique transformer technology is the basis of International Power Sources low cost, high performance, high
reliability DC/DC converter line. These converters are designed for telecommunication and industrial applications.
The converter design utilizes a push-pull topology operating at a fixed switching frequency of 300 kHz. By using
a fixed switching frequency, EMI filtering is made easier and less expensive.
The core technology is a patented, modular, and very low noise Flat TransformerTM which generates extremely low
leakage inductance and inter-winding capacitance, a combination not available in conventional transformers. In
addition, the Flat Transformer does not create hot spots, making the converters more reliable.
The use of direct bond aluminum base plates, forced current sharing in parallel rectifiers and the absence of hot
spots in the transformers allow the converter to have very low temperature gradients.
The converter’s internal temperature rise is less than 10°C above the base plate temperature, allowing base
plate temperature to be raised to 105°C.
The converters are manufactured in an ISO9001 approved facility utilizing advanced automated surface mount
technology and state of the art in-process test procedures.

Competitive Advantages
International Power Sources’ DC/DC converters are low cost, and can be delivered in a timely manner because
readily available standard off the shelf components are used. No custom parts are used.
International Power Sources’ DC/DC converters are extremely reliable because of the lower temperature gradient
and even thermal loading:
•
•
•
The highly derated multiple parallel rectifiers receive the exact same shared currents from
the use of Flat Transformer technology. This ensures even thermal loading on the rectifiers.
The Flat Transformer technology uses multiple cores. This coupled with the absence
of many turns eliminates hot spots in the transformer windings.
All heat generating components such as the Flat Transformers, inductors, rectifiers,
and MOSFETS are directly solder-bonded onto the aluminum base plate for maximum
transfer of heat out of the converter
International Power Sources’ DC/DC converters utilize simple push-pull topology with fewer components. The fixed
switching frequency ensures easier and less expensive EMI filtering. In addition, negligible leakage inductance of
Flat TransformersTM reduces the switching losses.

Application Notes
Thermal Consideration
Graph A shows the output power derating (in watts) with heat sink and without heat sink at various ambient tem-
peratures in still air conditions. If appropriate forced air is used with or without a heat sink, there is no power der-
ation as illustrated in Graph B. In such a case, the converter can be operated at its full output power rating.

Graph B: Output Power With Forced Air
Conversion Efficiency
Heat Sink
The graph below shows load current vs.
conversion efficiency specific to IBT200-301 only.
Graphs for other models available upon request.
The converter can be operated at full-load with
appropriate forced air cooling or by using a
lower thermal resistance heat sink.
Material: Aluminum Extrusion

Load Current vs Efficiency
Gate Control
Output Trimming
A remote on-off control pin is provided to enable
or disable the converter. When the Gate-In Pin 2
is at logic high (2.8 to 7V) or open circuited, the
converter is enabled. At logic low (<2.8V) the con-
verter is then disabled. If the control signal
has a common return with the primary side, one
can use a NPN transistor circuit to enable/disable
the converter. If the control signal is from the sec-
ondary, or anywhere else, an opto-coupler circuit
can be used.
Approximately 10% output voltage trimming
±
can be achieved by adding a potentiometer.
The recommended circuit connection technique
is shown below. The suggested minimum
resistance value is 5.1K .
