*Absolute maximum ratings are limiting values, to be applied individually, and

beyond which the serviceability of the circuit may be impaired. Functional

operability under any of these conditions is not necessarily implied. Exposure of

absolute maximum rating conditions for extended periods of time may affect

device reliability.

temperature devices; guaranteed by design and charac-

terization testing for industrial devices.

PIN DESCRIPTIONS

Pin

No.

Name

Function

1

–SENSE

Feedback loop connection for remote sensing

output voltage. Must always be connected to

output return for proper operation.

2

+SENSE

Feedback loop connection for remote sensing

output voltage. Must always be connected to

3

ADJUST

Adjusts output voltage setpoint.

4

STATUS

Indicates output voltage is within

±5% of

nominal. Active high referenced to –SENSE

(Pin 1).

Low level dc auxiliary voltage supply refer-

enced to input return (Pin 10).

6

INHIBIT

Power Supply Inhibit. Active low and refer-

enced to input return (Pin 10).

7

SYNC

Clock synchronization input for multiple

units; referenced to input return (Pin 10).

Current share pin which allows paralleled

units to share current typically within

±5% at

full load; referenced to input return (Pin 10).

9

TEMP

Case temperature indicator and temperature

shutdown override; referenced to input return

(Pin 10).

10

Input Return.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss

of functionality.
