NOTES
1)
Pins 1-3, 5-7 are 0.040” (1.02mm) diameter. with 0.080” (2.03mm)
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 - 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: 0.85 oz (24 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 core shown at left above is considered
part of the input/primary circuit and that the two ferrite cores shown
at the right above are considered part of the output/secondary 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.
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.
