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 state after the fault has been cleared. See Figures 3 and 5.

Output Voltage Programming

The output voltage of the converter can be adjusted or programmed via fixed resistors, potentiometers or voltage DACs. See Figure 8.

PARALLEL BUS - PR PIN

arallel 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 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.

.001 µF (500 V)

Figure 8 — Output voltage trim down and trim up circuit.

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.

PARALLEL BUS OUTPUT

375 V Input

• 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.
