CONTROL FUNCTIONS - PC PIN

Module Enable/Disable

Module Alarm

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 1.

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

state after the fault has been cleared. See Figures 2 and 4.

Primary Auxiliary Supply

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

in Figure 3, PC powers a module enabled LED.

Trim Down

Trim Up

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.

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 down resistor must be connected to the –Sense pin.

2. The trim up resistor must be connected to the +Sense pin.

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: vicorpower.com/tools.

Resistor values can be calculated for fixed trim up,

fixed trim down and for variable trim up or down.

In addition to trimming information, the web site and

the Applications Manual also include design tips,

applications circuits, EMC suggestions, thermal design

guidelines and PDF data sheets for all available Vicor

products.

CONTROL FUNCTIONS - PR PIN

Parallel Operation

+In

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

(N+M) redundancy and phased array capability. 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:

+Out

DC coupled single-wire interface. All PR pins are directly

connected to one another. This interface supports current

sharing but is not fault tolerant. Negative In pins must be tied

to the same electric potential. Up to three converters may be

paralleled by this method. See Figure 9.
