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 Transformer^TMwhich 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 Transformers^TMreduces the switching losses.

200 watt footprint.

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.

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.

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 .
