Feature Description (continued)

Forced Load Sharing (Parallel Operation with

– P option)

For additional power requirements, the power module

can be configured for parallel operation with active

load current sharing. Good layout techniques should

be observed for noise immunity when using multiple

modules in parallel. To implement active load sharing,

the following recommendations must be followed:

•

The parallel pins of all units in parallel must be

connected together. The path of these

connections should be as direct as possible, but

should not pass beneath the perimeter of the

module body, except immediately adjacent to the

parallel pin location.

•

Parallel modules must use the same 48V source.

The VIN (-) input pin is the return path for the

active current share signal of the parallel pin.

Separate 48V sources will prevent the active

current share return signal from being connected

to other modules.

•

The VIN (-) input connection should never be

disconnected from any of the parallel modules,

while another of the parallel modules is operating,

unless the VIN (+) pin, or the parallel pin is also

disconnected. The VIN (-) input provides the

internal logic ground and for the module’s primary

circuits, including the active current share circuit;

and there are sneak paths through the module’s

internal control ICs, when the VIN (-) pin is

disconnected (allowing the internal logic circuit to

float), while the parallel pin and VIN (+) pin are

connected to other operating modules. These

sneak paths do not cause permanent damage,

but do create false conditions that can affect the

module’s internal logic configuration.

•

The on/off pins of all modules should also be tied

together to the same external control circuitry, so

that the modules are turned on and off at the

same time, unless all parallel modules’ on/off pins

are tied to the input pins for automatic start upon

application of input voltage.

•

When modules in parallel applications contain the

auto-restart (4) option, it is required that the total

maximum load current value be less than 90% of

[n-1] times the individual module output current

rating, where n is the number of modules in

parallel. For example, if the application is using

three modules rated at 25A, then the maximum

total load shall be less than 0.9 x (3-1) x 25A =

0.9 x 2 x 25A = 45A. This insures that a single

module can shutdown without causing the total

load to exceed the capability of the remaining

operating module(s). The shutdown module can

then automatically restart, and assume its share

of the total load.

•

In all parallel applications (including applications

meeting the [n-1] sizing criteria discussed earlier),

if it is expected that a protective shutdown event

could cause more than one parallel module to

shutdown (for example, over temperature due to

a common fan failure, or gross over current

affecting two or more modules simultaneously),

then the use of the auto-restart (4) option is not

recommended. The auto-restart interval of these

modules is not synchronized to other modules,

nor is it precise. There will not be a successful

restart following multiple module shutdowns,

because the individual module’s restart timings

will be different. There will not be sufficient

module capacity to prevent the first module which

restarts from experiencing an over current, and

then again shutting down before the slowest

module has restarted. Meanwhile, the slowest

module will then restart, and then shutdown

during the interval the fastest module is waiting

for its next restart. And so on and so on. In these

cases, only latching shutdown modules should be

used; and either toggling the Vin source or the

on/off pin to simultaneously restart the modules,

following a shutdown, is advised.

When not using the parallel feature, leave the share

pin open.
