USER NOTES

Reflected Input Current

The reflected input current measurement (lir, see Electrical Characteristics) is performed according to the

test set-up of fig. 2.

Figure 2.

Softstart

To avoid heavy inrush current the output voltage

rise time is 10ms maximum in any condition of load.

Remote Sensing

The remote voltage sense compensation range is

for a total drop of 0.6V equally shared between the

load connecting wires.

It is a good practice to shield the sensing wires to

avoid oscillations.

See the connection diagram on figures 3, 4, 5, 6.

Remote ON/OFF

The module is controlled by the voltage applied

between the ON/OFF pin and -IN pin.

The converter is ON (Enable) when the voltage

applied is lower than 1.2 V (see Vien on Electrical

Characteristics).

The converter is OFF (Inhibit) for a control voltage

in the range of 8 to 18V (see Viinh).

When the pin is unconnected the converter is OFF.

Maximum sinking current is 1mA.

Module Protection

The module is protected against occasional and

permanent shortcircuits of the outp ut pins to

ground, as well as against output current overload.

It uses a current limiting protection circuitry, avoid-

ing latch-up problems with certain type of loads.

A latching crowbar output overvoltage protection is

activated when the output voltage exceeds the

typical value of 6.3V (see Electrical Charac-

teristics). A thermal non-latchingprotection disables

the module whenever the heatsink temperature

reaches about 85

°C.

Parallel Operation

To increase available output regulated power, the

module features the parallel connection possibility

with equal current sharing and maximum deviation

of 10% (two modules in parallel).

See the connection diagram on figures 3, 4, 5, 6.
