DESCRIPTION
Input standby current
The NNL10 series is part of a range of nonisolated, cost effective DC/DC converters offering
high precision output voltages from a nominal
3.0-5.5V or 10.0-14.0V intermediate bus where
isolation is not required. The series has been
recognized by Underwriters Laboratory (UL) to
UL 60950, file number E179522 applies.

1. A 330μF low ESR capacitor, approx 17mΩ at 100kHz to 300kHz must be fitted at the input to the NNL DC/DC converter to ensure
stability under all the operating conditions.
2. If components are required in tape and reel format suffix order code with -R, e.g. NNL10-10C-R.
All specifications typical at TA =25°C, nominal input voltage and rated output current unless otherwise specified.

APPLICATION NOTES
Output Voltage Trimming
The trimming input on the NNL10 allows
output voltage adjustment by ±10% of nominal
output voltage by connection of a resistor or by
application of a voltage to the Trim pin.
Fig.1
+VIN
To increase the output voltage, an external resistor
(Fig.1) or voltage source should be connected
between the Trim and the common pin.

ΔVOUT is the required change in output voltage in V.
To decrease the output voltage, an external resistor
(Fig. 2) or voltage source should be connected
between the Trim pin and the +VOUT pin.

Remote Sense
The remote sense function compensates for voltage drops from the output of the NNL10 to the
load point by regulating the output voltage at the load point. The voltage drop must not exceed
0.5V, although Trim and remote sense functions can be used in combination with each other, the
maximum voltage increase is 0.5V.

When increasing the output voltage the maximum output power

Output Sequencing

To simplify output sequencing,

the NNL10 series offers
offer
an optional single wire interconnection thatt performs
perform this
function. Using this con
connection, up to four devices
es can
be ‘daisy chained’ together,
geth with
th the ‘DC OK’ signal from
one converter signifying
ng that
t the
he next converter can
c be
enabled. A capacitor, simply connected to the daisy chain
link, provides a settablee delay in the sequence of the
converters starting.

Figure 3 shows a typical sequencing configuration, along
with the voltage outputs that it produces. As well as
reducing component count, making use of the ‘built-in’
sequencing capability means that only a single PCB track
