Functional Options
Remote Sense Pin Removed ("B" sufx)
These devices have their +Sense pin (pin 3) removed, and the feedback
loop is closed through the +VOUT path. The 10.5
resistor in Figure 1 is
installed in both standard and "B" models. See the Output Sense Function.
Horizontal Mounting ("H" sufx)
This packaging conguration 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 conguration can signicantly improve thermal performance.
See Thermal Derating for details.
Reversed pin vertical mounting ("J" sufx)
This additional mechanical conguration consists of a low-prole 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 Modications
Other options include a positive polarity (pull low to disable) on the On/Off
Control. Contact DATEL directly to discuss these and other possible modi-
cations.
