AFL28XXS Series

A conservative aid to estimating the total heat sink surface

When operating in the shared mode, it is important that

symmetry of connection be maintained as an assurance of area (A_{HEAT SINK}) required to set the maximum case

optimum load sharing performance. Thus, converter outputs temperature rise (∆T) above ambient temperature is given

by the following expression:

should be connected to the load with equal lengths of wire of

the same gauge and should be connected to a common

physical point, preferably at the load along with the converter

output and return leads. All converters in a paralleled set

must have their share pins connected together. This

arrangement is diagrammatically illustrated in Figure III

showing the output and return pins connected at a star

point which is located close as possible to the load.

∆T = Case temperature rise above ambient

As a consequence of the topology utilized in the current

sharing circuit, the share pin may be used for other functions.

In applications requiring only a single converter, the voltage

appearing on the share pin may be used as a “current

monitor”. The share pin open circuit voltage is nominally

+1.00V at no load and increases linearly with increasing

total output current to +2.20V at full load.

As an example, it is desired to maintain the case temperature

of an AFL2815S at ≤ +85°C while operating in an open area

whose ambient temperature is held at a constant +25°C;

then

Thermal Considerations

∆T = 85 - 25 = 60°C

Because of the incorporation of many innovative

technological concepts, the AFL series of converters is

capable of providing very high output power from a package

of very small volume. These magnitudes of power density

can only be obtained by combining high circuit efficiency

with effective methods of heat removal from the die junctions.

This requirement has been effectively addressed inside the

device; but when operating at maximum loads, a significant

amount of heat will be generated and this heat must be

conducted away from the case. To maintain the case

temperature at or below the specified maximum of 125°C,

this heat must be transferred by conduction to an

appropriate heat dissipater held in intimate contact with the

converter base-plate.

From the Specification Table, the worst case full load

efficiency for this device is 83%; therefore the power

dissipation at full load is given by

HEAT SINK

− 3.0 = 71in

Because the effectiveness of this heat transfer is dependent

on the intimacy of the baseplate/heatsink interface, it is

strongly recommended that a high thermal conductivity heat

transferring medium is inserted between the baseplate and

heatsink. The material most frequently utilized at the factory

during all testing and burn-in processes is sold under the

Thus, a total heat sink surface area (including fins, if any) of

71 in in this example, would limit case rise to 60°C above

ambient. A flat aluminum plate, 0.25" thick and of

approximate dimension 4" by 9" (36 in per side) would

suffice for this application in a still air environment. Note

that to meet the criteria in this example, both sides of the

plate require unrestricted exposure to the ambient air.

trade name of Sil-Pad® 400 . This particular product is an

insulator but electrically conductive versions are also

available. Use of these materials assures maximum surface

contact with the heat dissipater thereby compensating for

any minor surface variations. While other available types of

heat conductive materials and thermal compounds provide

similar effectiveness, these alternatives are often less

convenient and can be somewhat messy to use.
