AM1LT-NZ_13 Datasheet, PDF (3/3 Pages) AIMTEC – 1 Watt | DC-DC Converter

Minimum Load Requirement
Series AM1LT-NZ
1 Watt | DC-DC Converter
In order for this module to operate efficiently and reliably a minimum load of no less than 10% of its maximum needs to be
maintained at all times during operation.
NOTE: this converter should never be operated under no load. If it is required to operate the converter with less than 10%
load, it is recommended to install a resistor in parallel with the application load to draw additional current from the converter’s
output to maintain the minimum load condition, or use a converter rated at a lower power.

Recommended Filter Circuit
If it is required to decrease the input/output ripple, an “LC” filtering network may be connected to the input and output of the
converter, see above.
It should be noted that the inductance and the resonant frequency of the “LC” filtering network should differ from the DC/DC
converter switching frequency to avoid mutual interference.
The capacitance of the output filter capacitor must not exceed the values in the table below to avoid startup problems and
ensure safe and reliable operation.
It is not recommended to connect any external capacitor in the application field when output loading is less than 0.5 watt.
