Data Sheet

18 Vdc to 36 Vdc Input, 5 Vdc Output; 50 W to 150 W
FC050A, FC100A, FC150A Power Modules: dc-dc Converters;
Test Congurations
8-203(C).l
Note: Measure input reected-ripple current with a simulated source
inductance (LTEST) of 12 H. Capacitor CS offsets possible bat-
tery impedance. Measure current as shown above.
Figure 9. Input Reected-Ripple Test Setup
8-683(C).c
Note: All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module terminals to
avoid measurement errors due to socket contact resistance.

Measurement Test Setup
8-513(C)
Note: Use a 0.1 F ceramic capacitor. Scope measurement should
be made using a BNC socket. Position the load between
50 mm and 80 mm (2 in. and 3 in.) from the module.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. For the test conguration in Figure 9, a 33 F
electrolytic capacitor (ESR < 0.7
at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit. For other highly inductive source
impedances, consult the factory for further application
guidelines.
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standard,
i.e.,
UL-1950, CSA 22.2-950, and EN60950.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements.
If the input meets extra-low voltage (ELV) require-
ments, then the converter’s output is considered ELV.
The input to these units is to be provided with a maxi-
mum 15 A normal-blow fuse in the ungrounded lead.
Electrical Descriptions
Current Limit
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry and can endure current limiting for an unlim-
ited duration. At the point of current-limit inception, the
unit shifts from voltage control to current control. If the
output voltage is pulled very low during a severe fault,
the current-limit circuit can exhibit either foldback or
tailout characteristics (output-current decrease or
increase). The unit operates normally once the output
current is brought back into its specied range.
