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 (RoHS 5/6) - Tin/Lead over Nickel plate
Finish (RoHS 6/6) - Matte Tin 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: 2.4 oz. (69 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9) UL/TUV standards require a clearance greater than 0.04” (1.02mm) 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 consid-
ered part of the input/primary circuit.
10) The flanged pins are designed to permit surface mount soldering (avoiding
the wave soldering process) through the use of the flanged pin-in-paste tech-
nique.
11) M3 screws used to bolt unit’s baseplate to other surfaces such as a heatsink must not
exceed 0.100” (2.54mm) depth below the baseplate surface.
12) Applied torque per screw should not exceed 6 in-lb (0.7 Nm).
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(–)
Negative remote sense1
6
TRIM

7
SENSE(+)
Positive remote sense3
8
Vout(+)
Positive output voltage
Notes:
1. SENSE(–) should be connected to Vout(–) either remotely or at the con-
verter.
2. Leave TRIM pin open for nominal output voltage.
3. SENSE(+) should be connected to Vout(+) either remotely or at the con-
verter.
