GENERAL DESCRIPTION
Our AM2N-N series is a family of cost effective 2W
single and dual output DC-DC converters. These converters
combine plastic package in a 24-pin DIP compatible case
with high performance feature such as 6000VDC input/
output isolation voltage. Input voltages of 5, 12 & 24VDC
with output voltages of 5, 9, 12, 15, ±5, ±9, ±12, ±15VDC.
Full SMD-design and a 100% production test of parame-
ters ensures a high reliability in this product.

APPLICATION NOTE
For single output For dual output
Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection
against over-current and short-circuits. The
simplest method is to connect a self-recovery
fuse in series at the input end or add a circuit
breaker to the circuit.
Output Voltage Regulation and
Over-voltage Protection Circuit
The simplest device for output voltage
regulation, over-voltage and over-current
protection is a linear voltage stabilizer with
overheat protection that is connected to the
input or output end in series (see Figure 2).

Filtering
In some circuits which are sensitive to noise and ripple, a filtering capacitor may be added to the dc/dc output end and input end to reduce the noise and
ripple. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every
channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees the external capacitor table. To
get an extremely low ripple, an ìLCî filtering network may be connected to the input and output ends of the dc/dc converter, which may produce a more
significant filtering effect. It should also be noted that the inductance and the frequency of the ìLCî filtering network should be staggered with the dc/dc
frequency to avoid mutual interference (see figure 1).
Requirement on output load
To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of dc/dc converter in addition to a maximum load (namely
full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum output load is not less than 10% of the full load,
and that this product should never be operated under no load! If the actual output power is very small, please connect a resistor with proper resistance at the
output end in parallel to increase the load.
