APPLICATIONS
The WRA-ZMD-15W&WRB-ZMD-15W series is the
latest generation of high performance dc-dc converter
modules setting new standards concerning power density.
This product with 15W comes in a encapsulated, shielded
metal package with dimensions of only 2.0”x 1.0”x 0.4”
and occupies 50% less board space.
All models have ultra wide 4:1 input voltage range and
precisely regulated output voltages. Advanced circuit
design provides high efficiency up to 87% which allows a
operating temperature range of –40°c to +85°C (with
derating) Further features include remote On/Off, trimable
output and Basic Insulation. This product is fully compliant
to RoHS directive. Typical applications for these
converters are battery operated equipment, mobile
instrumentation, distributed power architectures in
communication and industrial electronics and everywhere
where space on PCB is critical.

Recommended circuit
All the WRA_ZMD-15W&WRB_ZMD-15W Series have been tested according to the following
recommended testing circuit before leaving factory . This series should be tested under load.
Never be test ed under no load (see Figure 1).
3. Efficiency Vs Output Power
If you want to further decrease the output ripple, you can increase capacitance properly or choose
capacitors with low ESR. However, the capacitance can't exceed the maximum capacitor load in the list.
