SIP Non-Isolated dc-dc Power Modules:
3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A
The power module should be connected to a low ac-imped-
ance input source. Highly inductive source impedances can
affect the stability of the module. An input capacitance must
be placed close to the input pins of the module, to filter ripple
current and ensure module stability in the presence of induc-
tive traces that supply the input voltage to the module.
Safety Considerations
For safety-agency approval of the system in which the power
module is used, the power module must be installed in com-
pliance with the spacing and separation requirements of the
end-use safety agency standard, i.e.,
UL60950, CSA
C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV),the input
must meet SELV requirements.
The power module has ELV (extra-low voltage) outputs when
all inputs are ELV.
The input to these units is to be provided with a maximum
20A time-delay fuse in the unearthed lead.
