GENERAL DESCRIPTION
Our AM1/4L-N series is a family of cost effective
1/4W single and dual output DC/DC converters.
These converters combine a miniature SMD package and high performance features such as a 1000 &
3000VDC input/output isolation voltages, continuous short circuit protection and a tight line / load
regulation.
96 models operate from input voltages of 3.3, 5, 12 and
24VDC producing output voltages of 3.3, 5, 9, 12, 15,

APPLICATION NOTE
General Application
In regular circuits, our company’s DC/DC converters may be used directly without any peripheral components (see Figure
2). The basic input/output isolation may be used to provide a group of simple isolated polar output power supplies or to
generate power supply lines of different voltages.
Voltage And Polarity Inversion
A key performance of this DC/DC converter is high electric isolation capability. Thus, only one DC/DC converter may allow
for several potential differences in the layout of circuit board. If necessary, you may connect the output end of the positive
to input ground, then the negative output end will generate a negative voltage (see Figure 1).
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 filtering capacitor sees the External Capacitor Table. To get an extremely low
ripple, a “LC” filter 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 “LC” filter network
should be staggered with the DC/DC frequency to avoid mutual interference (see Figure 3).
DUAL OUTPUT MODELS
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.
Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against over-current and shortcircuits. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the
circuits.
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 4).
Product Reliability
The MTBF is the mean time between failures under full load. If the actual load is less than 20% of the rated load or greater
than the rated load, then this productís reliability will be greatly reduced.
Input Polarity Protection
Under normal conditions, this productís input circuit has no protection against polarity inversion; the solution is to connect
a diode in series at the input.
