Derating Curve
Notes:
1. The specified maximum capacitive load is for each output.
2. Start up time is specified at the nominal Voltage input and with a constant
resistive load.
3. Load regulation is specified for a load change of 0% to 100%.
4. Cross regulation is specified with one output at full load while the other
output is varied from 25% to 100% load.
5. Output ripple is measured with a 1 μF ceramic capacitor and a 10 μF
electrolytic capacitor connected in parallel.
6. Transient recovery is measured to within a 1% error band for a load
step change of 25%. Single 3.3 & 5 VDC output models have a response
deviation of 5.0% Max.
7. Isolation voltage ratings are for 60 seconds.
8. With the addition of external filter and protection components, all models will
meet the requirements of EN 55032 classA.Suggested input circuits are shown
in the connection diagrams on page 3.Contact the factory for more information.
9. To meet the requirements of EN 61000-4-4 ( 2 kV), external components
are needed.The connection diagrams on page 3 shows external components
that would typically achieve this. Contact the factory for more information.
10. To meet the requirements of EN 61000-4-5 ( 2 kV), external components are
needed. This can be done as shown in the connection diagrams on page 3.
Contact the factory for more information.
11. Operation at no-load will not damage the unit, but they may not meet all
specifications.
12. It is recommended that a fuse be used on the input of a power supply for
protection. See the Model Selection table above for the correct rating.
Remote ON/OFF Control
The MD900x-RU may be started or shutdown by the control pin
input (pin 3). This input is current controlled. The unit operates
when this input is left open. When the input is “high” (current is
flowing into the pin), the converter shuts down. The input current
to this pin must be kept between 2 mA to 4 mA.
The diagram at right shows a simple input circuit for the control
pin. Closing the switch causes 2 - 4 mA to flow through the 1 k⍀
resister, shutting the unit off.

For applications that require meeting EMC standards, the diagrams below illustrate typi-
cal connections of the MD900xRU series. Some notes on this diagram (starting with the
input circuit) are:

3. The output filtering components C9 & C11 are high frequency, low ESR electrolytic
capacitors. Capacitors C10 & C12 are ceramic. Care must be taken in choosing
these capacitors not to exceed the capacitive load specification for the unit. Voltage
derating of capacitors should be 80% or above.
1. An external fuse should be used in all power module applications. The recommended
fuse is shown in the model chart on page 2.
2. To protect against voltage spikes, it is recommended that a TVS be used on the input.
A suggested value is given in the tables below.

Mechanical Dimensions
It is not required that the user connect the case ground
tabs (9 & 10 on the mechanical diagram) to the PCB.
However, connecting one or both tabs to a ground
plane on the PCB will help:

Key Features:
• 9W Output Power
For those applications that require high power den-
sity, but not a very wide input range, MPD offers the
MD900xRW series. These units also feature high power
density, a very high performance envelope and a wide
range of standard models. However, since thay are 2:1
input designs, they are offered at a lower cost.
