Input Voltage Range:
D12 = 10.8 to 13.2 Volts (12V nominal)
RoHS compliance ("-C" suffix)
Selected models use materials which are compatible with the Reduction of
Hazardous Substances (RoHS) directive.
Contact Murata Power Solutions Technologies (DATEL) for availability.
Functional Options
Remote Sense Pin Removed ("B" suffix)
These devices have their +Sense pin (pin 3) removed, and the feedback
loop is closed through the +VOUT path. The 10.57 resistor in Figure 1 is
installed in both standard and "B" models. See the Output Sense Function.
Horizontal Mounting ("H" suffix)
This packaging configuration reduces above-board height to 0.35" (8.89mm),
including the isolating pad. For "H" models, a thermally conductive, electri-
cally 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 configuration can significantly improve thermal
performance. See Thermal Derating for details.
Reversed pin vertical mounting ("J" suffix)
This additional mechanical configuration consists of a low-profile pin header
attached to the reverse side of the converter. It allows the LSN series to be
mechanically compatible with competitors' "keep out area."
Other Options and Modifications
Other options include a positive polarity (pull low to disable) on the On/Off
Control. Contact DATEL directly to discuss these and other possible modifi-
cations.
