CONTROL FUNCTIONS - PC PIN

Module Enable/Disable

Module Alarm

The module may be disabled by pulling PC below 2.3V 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 5.7V, PC can source up to 1.5mA. 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 up resistor must be connected to the +Sense pin.

2. The trim down 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.html.

Resistor values can be calculated for fixed trim up, fixed

trim down and for variable trim up or down cases for both

1st and 2nd Generation DC-DC converters.

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.

the same electric potential. See Figure 9.

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.

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

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

capacitors. This interface supports current sharing and is fault

tolerant except for the communication bus. See Figure 10.
