PIN DESCRIPTION

Pin

Function

Description

1,2

- Vin

Negative input voltage.

3,4

+ Vin

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

pin 1,2-3,4.

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

ON/OFF

The converter is ON (Enable) when the voltage applied to this pin with reference to pin 1,2

is lower than 1,2 V (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).

8

CASE

Case connection pin

9

+ SENSE

Senses the remote load high side. To be connected to pin 15,16,17 when remote sense is

not used.

10

- SENSE

Senses the remote load return. To be connected to pin 11,12,13,14 when remote sense is

not used. In parallel configuration, take care to connect all -SENSE pins together (see

figures 3,4,5,6).

11,12,

13,14

- OUT

-5V voltage return.

15,16,

17

+ OUT

+5V output voltage.
