APPLICATIONS
The RSB_T-3W Series are specially designed
for applications where a wide range input
voltage power supplies are isolated from the
input power supply in a distributed power
supply system on a circuit board.

These products apply to:
1) Where the voltage of the input power
supply is wide range (voltage range: 2:1);
2) Where isolation is necessary between
input and output
(isolation voltage =1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

Recommended Circuit
All the RSB_T-3W Series have been tested
according to the following recommended testing
circuit before leaving factory. This series should
be tested under load(Figure 1).

If you want to further decrease the input/output
ripple, you can increase capacitance properly or
choose capacitors with low ESR. However, the
capacitance should not be too high(Table 1)

External Capacitor
Although this series of DC/DC converter can
work without external capacitor, in order to keep
an optimum performance, however, it needs
external capacitor. (Table 2)

When it is used in unregulated power supply,
be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed
the module standard. Input current of power
supply should afford the startup current of this
kind of DC/DC module (Figure 2)

APPLICATION NOTE
Requirement on Output Load
To ensure this module 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 out put load is not less
than 10% Of the full load, If the actual load is less below the specified minimum load, the output
ripple of this type of DC/DC converter may increase drastically. If the actual output power from
the load in your circuit is very small, please connect a resistor with proper resistance at the
output end to in parallel to increase the load, or use our company’s other products with a lower
rated output power.
