APPLICATIONS
The B_XLSR&B_XLD series are specially
designed for applications where a group of
polar 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 fixed (voltage variation ≤±5%);
2) where isolation is necessary between input
and output (isolation voltage ≥1000VDC);
3) where the regulation of the output voltage
and the output ripple noise are demanded.

To ensure this module can operate efficiently and
reliably, During operation,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,or use our company's products with
a lower rated output power(QB_XLDR /QB_XLSR
series).

If you want to further decrease the input/output ripple,
an "LC" filtering network may be connected to the input
and output ends of the DC/DC converter, see (Figure 1).
*Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARACTERISTICS
Temperature Derating Graph
It should also be noted that the inductance and the
frequency of the "LC" filtering network should be
staggered with the DC/DC frequency to avoid mutual
interference. 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 (Table 1).

RECOMMENDED FOOTPRINT
Overload Protection
Top view,grid:2.54mm(0.1inch)
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.

Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, 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.or use our company's products with a lower rated output power .
No parallel connection or plug and play.
Use dual output simultaneously, forbid opening output
pin(0V)to use as single output.

Website:http://www.microdc.cn
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
REACH COMPLIANT INFORMATION
This series has proven that this product does not contain harmful chemicals, it also has
harmful chemical substances through the registration, inspection and approval.
