Product Overview

Absolute Maximum Ratings

This DC-DC converter module uses

second generation power processing, control

and packaging technologies to provide the

performance, flexibility and cost effectiveness

expected of a mature Power Component.

For example, a plated-cavity core transformer

couples widely separated primary and

secondary windings, resulting in low in-to-

out parasitic capacitance and noise.

High frequency ZCS/ZVS switching,

advanced power semiconductor packaging

and thermal management provide high

power density with low temperature

gradients. Extensive use of silicon

integration results in 1/3 the part count

of a first generation converter.

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, 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.

Figure 7—Output voltage trim down circuit.

Figure 8—Output voltage trim up circuit.

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 values calculated automatically:

Resistor trim calculators are available on Vicor’s

web site at URL: www.vicr.com/tools.html

or by requesting a copy of Vicor’s

Applications Manual on a CD ROM.

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 on

CD ROM also include design tips,

applications circuits, EMC suggestions,

thermal design guidelines and PDF data

sheets for all available Vicor products.

CONTROL FUNCTIONS - PR PIN

Compatible interface architectures include the following:

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

nected to one another. This interface supports current sharing

but is not fault tolerant. Minus In pins must be tied to the same

electric potential. See Figure 9.

Parallel Operation

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 ^.001µF (500V) capacitors.

This interface supports current sharing and is fault tolerant

except for the communication bus. See Figure 10.
