DESCRIPTION
The NNL10 series is part of a range of nonisolated, cost effective DC/DC converters
offering high precision output voltages from a
nominal 3.0–5.5 or 10.0–14.0 intermediate
bus where isolation is not required. Available
in both SMD and SIP mechanical formats.

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.

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.

FIG.4
To simplify output sequencing, the
NNL10 series offers an optional single
wire interconnection that performs this
function. Using this connection, up to
four devices can be 'daisy chained'
together, with the 'DC OK' signal from
one converter signifying that the next
converter can be enabled. A
capacitor, simply connected to the
daisy chain link, provides a settable
delay in the sequence of the
converters starting.
Typical capacitor values and
corresponding delays are shown in
the table below.
Figure 4 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 is required for a full
sequencing solution.
