Functional Options
Remote Sense Pin Removed ("B" suffi x)
These devices have their +Sense pin (pin 3) removed, and the feedback
loop is closed through the +V
installed in both standard and "B" models. See the Output Sense Function.
Horizontal Mounting ("H" suffi x)
This packaging confi guration reduces above-board height to 0.35" (8.89mm)
including the "pad." For "H" models, a thermally conductive, electrically
insulating "pad" is factory installed on the output inductor. The pad material is
Bergquist Sil Pad 400. The pad size is 0.4 x 0.5 x 0.009 inches (10.16 x 12.7
x 0.23mm). This confi guration can signifi cantly improve thermal performance.
See Thermal Derating for details.
Sense Pins
Note: If the sense pin is installed, it must be connected to either a remote
load or to +output at the converter pins. Do not leave sense unconnected.

Reversed pin vertical mounting ("J" suffi x)
This additional mechanical confi guration consists of a low-profi le pin header
attached to the reverse side of the converter. It allows the LSN series to be
mechanically compatible with Tyco's "keep out area."
Other Options and Modifi cations
Other options include a positive polarity (pull low to disable) on the On/Off
Control. Contact Murata Power Solutions (DATEL) directly to discuss these
and other possible modifi cations.
