Module Enable/Disable

The module may be disabled by pulling PC below 2.3 V with

respect to the –Input. This may be done with an open collector

transistor, relay, or optocoupler. Multiple converters may be

disabled with a single transistor or relay either directly or via

“OR’ing” diodes. See Figure 2.

Primary Auxiliary Supply

At 5.7 V, PC can source up to 1.5 mA. In the example shown

in Figure 4, PC powers a module enabled LED.

Module Alarm

The module contains “watchdog” circuitry which monitors

input voltage, operating temperature and internal operating

parameters. In the event that any of these parameters are

outside of their allowable operating range, the module will

shut down and PC will go low. PC will periodically go high

and the module will check to see if the fault (as an example,

overtemperature) has cleared. If the fault has not been cleared,

PC will go low again and the cycle will restart. The SC pin

will go low in the event of a fault and return to its normal

Parallel Operation

The PR pin supports paralleling for increased power with N+1

(N+M) redundancy. Modules of the same input voltage, output

voltage, and power level will current share if all PR pins are

suitably interfaced.

Compatible interface architectures include the following:

AC coupled single-wire interface. All PR pins are connected

to a single communication bus through 0.001 µF (500 V)

capacitors. This interface supports current sharing and is fault

tolerant except for the communication bus. Up to three

converters may be paralleled by this method. See Figure 9.

Transformer coupled interface. For paralleling four or more

converters a transformer coupled interface is required. See

Figure 10.

For details on parallel operation please refer to the

Design Guide & Applications Manual for Maxi, Mini, Micro Family.

Output Voltage Programming

The output voltage of the converter can be adjusted or

programmed via fixed resistors, potentiometers or voltage

DACs. See Figure 8.

Trim Down

1. This converter is not a constant power device – it has a

constant current limit. Hence, available output power is

reduced by the same percentage that output voltage is

trimmed down. Do not exceed maximum rated output current.

2. The trim down resistor must be connected between the SC

and -S pins. Do not bypass the SC pin directly with a

capacitor.

Trim Up

1. The converter is rated for a maximum delivered power. To

ensure that maximum rated power is not exceeded, reduce

maximum output current by the same percentage increase in

output voltage.

2. The trim up resistor must be connected between the SC

and +S pins. Do not bypass the SC pin directly with a

capacitor.

3. Do not trim the converter above maximum trim range

(typically +10%) or the output over voltage protection

circuitry may be activated.

Trim resistor values calculated automatically:

On-line calculators for trim resistor values are available on the

vicor website at:

asp.vicorpower.com/calculators/calculators.asp?calc=1

Resistor values can be calculated for fixed trim up, fixed trim

down and for variable trim up or down.

Figure 11 —N+1 module array output connections.

• The +Out and –Out power buses should be designed to

minimize and balance parasitic impedance from each

module output to the load.

• The +Sense pins must be tied together to form a

+Sense bus. This must be Kelvin connected to +Out

at a single point. The –Sense pins should be tied

together to form a –Sense bus. This must be Kelvin

connected to –Out at a single point.

• At the discretion of the power system designer,

a subset of all modules within an array may be

configured as slaves by connecting SC to –S.

• OR’ing diodes may be inserted in series with the

+Out pins of each module to provide module

output fault tolerance.

• The +Sense and -Sense leads should be routed in close

proximity to each other on the printed circuit board. If

wires are used to connect the converters on a PCB to

an external load, the Sense leads should be twisted

together to reduce noise pickup.
