LSN10A-D5 Datasheet, PDF (15/15 Pages) Murata Manufacturing Co., Ltd. – Non-Isolated, 5VIN, 1-3.8VOUT 10 Amp DC/DC In SIP Package

EMI CONDUCTED/RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of MPS’s LSN D5 DC/
DC Converters have been characterized for conducted and radiated emissions
in our EMI/EMC laboratory. Testing is conducted in an EMCO 5305 GTEM test
cell utilizing EMCO automated EMC test software. Conducted/Radiated emis-
sions are tested to the limits of FCC Part 15, Class B and CISPR 22 (EN 55022),
Class B. Correlation to other specifications can be supplied upon request. For
corresponding emissions plots to FCC and CISPR 22 for model LSN-5/10-D12
(the highest possible output power model) and for LSN-2/10-D3 (representing
the highest input current models) see LSN-10A D12 and LSN-10A D3 data
sheets for reference. These respective curves are representative of all LSN
models. Contact MPS’s Applications Engineering Department for more details.

Single Output LSN-10A Models
Non-Isolated, 5VIN, 1-3.8VOUT
10 Amp DC/DC In SIP Package
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 "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 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 Tyco's "keep out area."
Other Options and Modifications
Other options include a positive polarity (pull low to disable) on the On/Off Con-
trol. Contact MPS directly to discuss these and other possible modifications.
