TYPICAL CHARACTERISTICS
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).
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 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 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.
