Pin No.

Name

Function

1

Vin(+)

Positive input voltage

2

ON/OFF

TTL input to turn converter

on and off, referenced to

Vin(-), with internal pull up.

3

Vin(-)

Negative input voltage

4

Vout(-)

Negative output voltage

5

SENSE(-)

6

TRIM

7

SENSE(+)

8

Vout(+)

Positive output voltage

Notes:

1. SENSE(–) should be connected to Vout(–) either remotely or at the converter.

2. Leave TRIM pin open for nominal output voltage.

3. SENSE(+) should be connected to Vout(+) either remotely or at the converter.

NOTES

1) Pins 1-3, 5-7 are 0.040” (1.02mm) diameter with 0.080” (2.03

mm) diameter standoff shoulders.

2) Pins 4 and 8 are 0.062” (1.57 mm) diameter with 0.100” (2.54

mm) diameter standoff shoulders.

3) Other pin extension lengths available. Recommended pin length

is 0.03” (0.76mm) greater than the PCB thickness.

4) All Pins: Material - Copper Alloy

Finish - Tin/Lead over Nickel plate

5) Undimensioned components are shown for visual reference only.

6) All dimensions in inches (mm)

Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)

x.xxx +/-0.010 in. (x.xx +/-0.25mm)

7) Weight: 1.2 oz. (34 g) typical

8) Workmanship: Meets or exceeds IPC-A-610C Class II

between input and output for Basic insulation. This issue should be

considered if any copper traces are on the top side of the user’s

board. Note that the ferrite cores are considered part of the input/pri-

mary circuit.

10) The flanged pins are designed to permit surface mount

soldering (allowing to avoid the wave soldering process)

through the use of the flanged pin-in-paste technique.
