The NGL 16.5W dc-dc Converter is part of NG
Series, which rapresents the Magnetek’s Family
of High Efficiency Low Power DC-DC Converters.
These modules feature high reliability, high
efficiency and a widely varying range of input
voltages (from 19.2 to 72 Vdc) with the possibility
of a careful regulation of output voltage, so they
are ideally suited for Telecommunications,
Industrial and Computer applications.
The compact size of these units make them ideal
for inclusion in original design of systems which
demand small size, low cost and high reliability.
The standard feature set includes output trim
allowing the user to adjust the output voltage to
a value within ±10% of the nominal output
voltage, and the clock input for synchronization
to an external secondary clock, while the case
ground pin is optional.

Output voltage trim allows the user to adjust the output voltage to a pre-defined value within ±10% of the nominal output voltage.
If an external resistor (RTdown) is connected between the Trim and -Vout pins, the output voltage decreases (see wiring * in Figure 3 ).
If an external resistor (RTup) is connected between the Trim and +V pins, the output voltage increases (see wiring ** in Figure 3).

No external output capacitance.
The module is provided with hysteretic control of input line between 19.2V - 72V.
CAUTION: To preserve the module’s flexibility, internal fusing is not included; however, to achieve the maximum system protection, input
fusing is always highly recommended based on inrush current and maximum input current.

Feature Descriptions
Current Limit
For protection in a output overload condition, the unit is equipped with an hiccup current limit protection so that it is able
to work on short circuit condition for an undefinite time on all operating temperature range.
The unit operates normally once the output current is brought back into its specified range.
Syncronization
The Ck_Input Pin allows the synchronization of the fixed switching frequency to an external clock. This function is
compatible with a 3.3Vpp signal, coupled through a 1nF capacitor on a impedance ³ 3kohm.
However the power supplier start-up even without any sync. clock.
