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

Output voltage trim2
7
SENSE(+)
Positive remote sense3
8
Vout(+)
Positive output voltage
Notes:
1. SENSE(-) may be connected to Vout(-) or left open.
2. Leave TRIM pin open for nominal output voltage.
3. SENSE(+) may be connected to Vout(+) or left open.
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
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 considered
part of the input/primary circuit.
10) The flanged pins are designed to permit surface mount sol-
dering (allowing to avoid the wave soldering process)
through the use of the flanged pin-in-paste technique.
