PIN DESCRIPTION

Pin

Function

Description

1

Inhibit

The module is disabled by a high logic level applied to this pin.

2

Reset

Reset output (GS-R405S only).

3

+ Input

DC input voltage. Recommended maximum voltage is 46V.

4

Input GND

Return for input voltage source.

5

Oscillator

100kHz oscillator output. To be connected to Sync (pin 6) input if the unit is a master and

left open if it is a slave (GS-R400VB only). See fig. 5.

6

Sync

Synchronization input. To be connected to the Oscillator output (pin 5) of the master (GS-

R400VB only). See fig. 5.

7

Current limiting

A resistor (

≥ 2.2kΩ) connected from this pin to pin 9 sets the current limiting level

(GS-R400VB only).

8

Output GND

Return for output current path.

Internally connected to pin 4.

9

– Sense

Senses the remote load return. Must be tied to pin 8 when the remote sensing feature is

not used. See fig. 1.

10

+ Sense

Senses the remote load high side. Must be tied to pin 11 when the remote load sensing

feature is not used. See fig. 1.

11

+ Output

Regulated DC output voltage.

12

Program

A resistor (

≤ 18kΩ) connected between this pin and pin 10 sets the output voltage

(GS-R400V and GS-R400VB only).
