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
Output voltage trim2
7
SENSE(+)
Positive remote sense3
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
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/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.
