Design Considerations
The ATM030 module should be connected to a low-
impedance source. A highly inductive source can
affect the stability of the module. An input capacitor
must be placed directly adjacent to the input pin of
the module, to minimize input ripple voltage and
ensure module stability.
To minimize input voltage ripple, low-ESR ceramic
capacitors are recommended at the input of the
module. Figure 28 shows the input ripple voltage for
various output voltages at 30A of load current with
1x47 µF or 2x47 µF ceramic capacitors and an
input of 3.3V.
Figure 28. Input ripple voltage for various
output voltages with 1x47 µF or 2x47 µF ceramic
capacitors at the input (30A load). Input voltage
is 3.3V.
Safety Considerations
For safety agency approval the power module must
be installed in compliance with the spacing and
separation requirements of the end-use safety
agency standards, i.e., UL 60950, CSA C22.2 No.
60950-00, EN60950 (VDE 0850) (IEC60950, 3
edition) Licensed.
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 extra-low voltage (ELV)
outputs when all inputs are ELV.
An input fuse for the module is recommended. As
an option to using a fuse, no fuse is required, if the
module is powered by a power source with current
limit protection and the module is evaluated in the
end-use equipment.
