PIN DESCRIPTION

Pin

Function

Description

1- IN

Negative input voltage.

2+ IN

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

pin 1-2.

3

ON/OF F

The converter is ON (Enable) when the voltage applied to this pin with reference to pin 1 is

lower than 1.2V (see Vien). The converter is OFF (Inhibit) for a control voltage in the range

of 8 to 18V. When the pin is unconnected the converter is OFF (Inhibit).

4

CASE

Case connection pin.

5

SYNC

Synchronization pin. See figures 3, 4, 5, 6. Open when not used.

6

PARALLEL

Parallel output. See figures 3, 4, 5, 6. Open when not used.

7

+ SENSE

Senses the remote load high side. To be connected to pin 11,12 when remote sense is not

used.

8

- SENSE

Senses the remote load return. To be connected to pin 9,10 when remote sense is not

used. In parallel configuration, take care to connect all -S pins together (see figures 3,4,5,6).

9,10

- OUT

Fixed output voltage return.

11,12

+ OUT

Fixed output voltage.
