2 Functional Description
Typical Connections
The Ag9900 requires minimal external components as shown in Figure 3.
C1 must be fitted for output stability and should be a minimum of 100µF. This capacitor
should be positioned as close to the output pins as possible. C1 is also required to
handle load step change and reduce the output ripple. For applications where the output
needs to cope with high load step changes, or to reduce the output ripple we
recommend using a low ESR electrolytic as this reduces the output ripple. Also a low
ESR capacitor is essential for operation below 0°C.
BR1 and BR2 can be inexpensive bridge rectifiers, for example MB4S or MB6S.

The output adjust input (ADJ) is optional, it is provided to give greater flexibility to the
Ag9900 product range. Further information on using these inputs can be found in
Section 2.3.1.
The Ag9900 must always supply a minimum current; see Section 8.3 - Minimum Load
for more information. When operated below this level the Ag9900 will emit a low level
audible noise. The reason that the module emits this noise is due to the dc/dc converter
running in discontinuous mode.

V2.4 April 2020
Datasheet
Ag9900
Ultra Miniature PoE Module
If this audible noise is not an issue, then the Ag9900 can work safely with a much
smaller load. But to ensure that the PSE has a sufficient load to meet its Maintain Power
Signature (MPS), it would be advisable not to operate the Ag9900 below the specified
minimum load.
Input
The Ag9900 is compatible with equipment that uses Alternative A (power on data pair)
or Alternative B (power on spare pair) options, see Figure 4. It is specified that the PSE
does not apply power to both outputs at the same time (Refer to IEEE802.3af for more
information).

2.2.1 PD Signature
When the Ag9900 is connected to the Cat5e cable, it will automatically present a
Powered Device (PD) signature to the Power Sourcing Equipment (PSE) or Midspan
Equipment, when requested. The equipment will then recognise that a powered device
is connected to that line and supply power.
2.2.2 Power Classification
The Ag9900 is set to Class 0 (0.44 Watts to 12.95 Watts) operation.
2.2.3 Start-up Power
It is important that during start-up the Ag9900 input voltage is ≥42V, this will ensure that
the module powers up correctly. Once the dc/dc converter is up and running the module
will work normally even if the input voltage is reduced to its minimum level of 36V.
When using an IEEE802.3af compliant PSE this will not be an issue, as the minimum
output voltage of the PSE must be ≥44V.

Figure 6: Output Filtering
The simplest and cheapest solution is shown in Figure 6 - Output Filter A. Taking the
Ag9912M as an example, this will reduce the ripple and noise to typically 120mVp-p at
maximum load. Adding a PI filter, as shown in Figure 6 – Output Filter B, will take the
ripple and noise level down further to typically 25mVp-p.

Input Protection
The Ag9900 must be protected from over-voltages exceeding the 80V maximum rated
surge input voltage. An inexpensive but effective solution can be achieved by
connecting a tranzorb diode across the input; see Figure 7.

Thermal Protection
The standard Ag9900M does not have built-in thermal protection. If this module is
intended to be used in high ambient temperatures >50°C then we would recommend
either the Industrial temperature version Ag9900MT or the Ag9900LP (both include
thermal protection) to be used.
The thermal protection reduces the output power, see Figure 8 through Figure 14, to
ensure that the maximum component temperature is not exceeded. Full output power
will be restored when the ambient temperature drops back down into the safe operating
range.

4 Operating Temperature Range
Because the Ag9900 is a power component, it will generate heat, so it is important that
this be taken into consideration at the design stage.
The heart of the Ag9900 is a DC/DC converter, which like any other power supply will
generate heat. The amount of heat generated by the module will depend on the load it
is required to drive, and the input voltage supplied by the PSE. The information shown
within this section of datasheet is referenced to a nominal 48Vdc input voltage supplied
by the PSE.
The Ag9900M has a maximum ambient operating temperature of 70˚C without any
heat-sinking, while the Ag9900MT and Ag9900LP able to operate up to 85˚C while
heatsinking to a host PCB; see below Figure 8 through Figure 14. These results were
performed in an environment chamber - Associated Environmental System SD-302.The
performance of the Ag9900M can be improved by forcing the airflow directly over the
part, and by using a thermal pad such as Bergquist .1” Ultra soft gap pad or thermal
paste such as thermally conductive Oxime Cure paste. The customers PCB can then be
thermally mounted (using a Bergquist 0.1” Ultra soft gap pad) to the chassis of the host
equipment by using the thermal relief pads (see Figure 15 and application note “ANX-
POE-Thermal-Considerations” for more information).
The output stage of the Ag9900M has no built-in thermal protection; however thermal
protection is available with the Industrial temperature version Ag9900MT or Ag9900LP
module. To prevent the module from being damaged it is recommended that the module
be powered by an IEEE 802.3af compliant PSE or midspan equipment. However the
Ag9900 may be powered by a user designed power supply which should include
thermal and over current protection and be current limited to 400mA.

Thermal Considerations
Each application is different; therefore it is impossible to give fixed and absolute thermal
recommendations. Due to the small size of this module, it is important that as much
heat as possible is drawn away from it. It is also important that any enclosure has
sufficient ventilation for the Ag9900 and a direct airflow if possible.
One simple method for drawing some of the heat away from the Ag9900 is by means of
power planes connected to the +VDC and -VDC pins of the Ag9900. This technique can
be used to draw heat away from the DC/DC converter via the output pins.
These power planes must be on the outer layers of the PCB and the best results are
achieved by having power planes on both sides of the main board with multiple through-
hole connections. An example of this is shown in Figure 15 with an Ag9900M module.

A method that we would recommend when using the Ag9900 series is the use of a
thermal gap pad or thermal paste, such as Berquist ultra soft 0.1in or Thermally
conductive Oxime Cure paste, be placed underneath the Ag9900 PCB as shown below
in Figure 16. The gap pad or paste must fully cover the components on the bottom side
of the PCB to provide the best possible thermal conduction through the material to the
customers PCB.

It is important to remember that the ESR of the external electrolytic capacitors will
increase considerably when the ambient temperature falls below 0°C. If the Ag9900 is
going to be used in applications where the ambient temperature can fall below 0°C,
selection of appropriate output filter components must be done at the design stage.

5 Typical Application
The Ag9900 can be used in numerous applications. In the example shown in Figure 17,
the data outputs from the switch are connected to the inputs of a midspan. The midspan
will then add power (to the data) on each output that supports Power over Ethernet
(PoE).
In this example port 1 is connected to an Ethernet camera and port 2 is connected to a
wireless access point, both of these devices have a built-in Ag9900. When the midspan
is switched on (or when the device is connected), the midspan will check each output
for a PoE signature. On ports 1 and 2 the Ag9900 will identify themselves as PoE
enabled devices and the midspan will supply both data and power to these peripherals.
The other ports (shown in this example) will not have a PoE signature and the midspan
will only pass the data through to these peripherals. The midspan will continuously
monitor each output to see if a PoE enabled device has been added or removed.

6 Isolation
To meet the safety isolation requirements of IEEE802.3af section 33.4.1 a Powered
Device (PD) must pass the electrical strength test of IEC 60950 sub clause 6.2. This
calls for either a) 1500Vac test or b) 1500Vdc impulse test. The Ag9900 is specified to
meet the 1500Vdc impulse test. It is also important that the tracks on either side of the
isolation barrier have at least a 3mm clearance, see Figure 10 & Figure 14 for more
information.
Layout Consideration
Figure 18 shows the position of the isolation barrier, this area must be kept clear of
tracks under the Ag9900 module.

7 EMC
The Ag9900 uses a dc/dc converter with pulse width modulation, so care does need to
be taken to minimise emissions.
The Ag9900 is designed to meet EN55032 Class B (pre-compliance test results are
available from Silvertel) however, because the Ag9900 will only be one component
within your system, it is impossible to say whether the final product will pass EMC
testing without the need for additional filtering. Figure 19 shows our recommended EMC
Filter configuration for the Ag9900. For more information, tips and suggestions refer to

Note 1: Electrical characteristics are identical for the Ag9900M and Ag9900MT variants.
Note 2: Typical figures are at 25°C with a nominal 48V supply and are for design aid only. Not Guaranteed
Note 3: The module can emit an audible noise, if operated at less than the stated minimum ILOAD and cause the PSE to fail its MPS.
Note 4: The Ag9912 output must not exceed 12W.
Note 5: Measured with external filter A. The output ripple and noise can be reduced further with external filter B, see Section 2.3.2.
Note 6: >200mohm short due to thermal limitation.
