NOTES

1) M3 screws used to bolt unit’s baseplate to other surfaces (such as a

heatsink) must not exceed 0.100” (2.54 mm) depth below the surface

of the baseplate.

2) Applied torque per screw should not exceed 6in-lb. (0.7 Nm).

3) Baseplate flatness tolerance is 0.004” (.10mm) TIR for surface.

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

diameter standoff shoulders.

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

diameter standoff shoulders.

6) Other pin extension lengths available. Recommended pin length is

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

7) All Pins: Material - Copper Alloy- Finish - Matte Tin over Nickel plate

8) Undimensioned components are shown for visual reference only.

9) Weight: 2.15 oz. (60.9 g) typical

10) All dimensions in inches (mm)

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

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

PIN DESIGNATIONS

Pin

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(–)

Negative remote sense (See note 1)

6

TRIM

Output voltage trim (See note 2)

7

SENSE(+)

Positive remote sense (See note 3)

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.
