NOTES
1) M3 screws used to bolt unit’s baseplate to other surfaces (such as
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 1-4, 6-8 are 0.040” (1.02mm) diameter, with 0.080” (2.03mm)
diameter standoff shoulders.
5) Pins 5 and 9 are 0.080” (2.03 mm) diameter with 0.125” (3.18mm)
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 (RoHS 6/6): Matte Tin over Nickel plate
8) Undimensioned components are shown for visual reference only.
9) Weight: 4.3oz (123g)
10) All dimensions in inches (mm) Tolerances: x.xx +/-0.02 in. (x.x
+/-0.5mm) x.xxx +/-0.010 in. (x.xx +/-0.25mm)
11) Workmanship: Meets or exceeds IPC-A-610C Class II
12) 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
Reserved
Not connected
4
Vin(–)
Negative input voltage
5
Vout(–)
Negative output voltage
6
SENSE(–)
Negative remote sense; see note 1
7
TRIM
Output voltage trim; see note 2
8
SENSE(+)
Positive remote sense; see note 3
9
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.
