AFL120XXD Series

When operating in the shared mode, it is important that A conservative aid to estimating the total heat sink surface

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

optimum load sharing performance. Thus, converter out- erature rise (∆T) above ambient temperature is given by

converter output and return leads. All converters in a par-

alleled 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.

where

∆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 func-

tions. In applications requiring only a single converter, the

voltage appearing on the share pin may be used as a “totall

current monitor”. The share pin open circuit voltage is nomi-

nally +1.00v at no load and increases linearly with increas-

ing total output current to +2.20v at full load. Note that the

current we refer to here is the total output current, that is,

the sum of the positive and negative outout currents.

As an example, assume that it is desired to operate an

AFL12015D while holding the case temperature at T_C

+85°C in an area where the ambient temperature is held to

≤

a constant +25°C; then

∆T = 85 - 25 = 60°C

Thermal Considerations

Because of the incorporation of many innovative techno-

logical 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 effec-

tive methods of heat removal from the die junctions. This

requirement has been effectively addressed inside the de-

vice; 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 tem-

perature 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 effi-

ciency for this device is 83% @ 100 watts: thus, power

dissipation at full load is given by

P = 100•

and the required heat sink area is

HEAT SINK

− 3.0 = 56.3 in²

Since 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 fac-

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

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

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

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

mate dimension 4" by 7" (28 in per side) would suffice for

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

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 +25°C ambient air.

an insulator but electrically conductive versions are also

available. Use of these materials assures maximum sur-

face contact with the heat dissipater thereby compensating

for any minor surface variations. While other available types

of heat conductive materials and thermal compounds pro-

vide similar effectiveness, these alternatives are often less

convenient and can be somewhat messy to use.
