PIN DESCRIPTION

Pin

Function

Description

1

- IN

Negative input voltage.

2

+IN

Positive input voltage. Unregulated input voltage (typically 48V) must be applied between

pins 1-2. The input section of the DC-DC converter is protected against reverse polarity by

a series diode. No external fuse is required. Input is filtered by a Pi network.

3

ON/OFF

Logically compatible with CMOS or open collector TTL. The converter is ON (Enable)

when the voltage applied to this pin with reference to pin 1 is higher than 1.8V. The

converter is OFF (Inhibit) for a control voltage lower than 1.2V. When the pin is

unconnected the converter is ON (Enable).

4

+ SENSE

Senses the remote load high side. To be connected to pin 6 when remote sense is not

used.

5

- SENSE

Senses the remote load return. To be connected to pin 7 when remote sense is not used.

6

+ OUT

Output voltage.

7

- OUT

Output voltage return.
