3 Introduction
This Manual is a guide to using the EvalAg7300 evaluation board fitted with a Silvertel
Ag7300 High Power Isolated Boost Converter module for use in a wide variety of point of
load (PoL) and DC-DC converter applications, including IEEE802.3bt Power over Ethernet
(PoE) Power Sourcing Equipment (PSE) applications.
While this evaluation board has been designed following Silvertel's recommendations, it
should not be considered as a reference design as it features circuity included solely for
the purposes of evaluation that are not be required for proper operation.

Evaluation Board
4 Input
Supply
The EvalAg7300 evaluation board should be powered by a DC Power supply connected to
J1 and J2 binding posts using 4mm Banana connectors, bare wire, or fork connectors.
This supply should deliver between 18-36V. The Ag7300 can output up to 120W of
continuous output power, at this output power the Ag7300 will dissipate up to 16W. Any
power source should be suitably rated for the desired output power, the power dissipation
of the Ag7300 and any transmission power losses. For example, a 24V supply should be
capable of supplying up to 7A if the full output power is to be drawn.
Output Voltage Adjust
The output voltage of the Ag7300 module can be adjusted up or down by changing the
location of the jumper LK1. The EvalAg7300 is fitted with two adjust resistors. The down
adjust resistor R1, is fitted with a 510kΩ resistor. And the up adjust resistor R6, which is
fitted with a 0Ω resistor to allow for the maximum adjust change of the Ag7300LPB
module.
With no jumper present on LK1, the module will default to its nominal 55.5V output.
To increase the output voltage, insert the jumper to LK1 in the left position, so that the link
is between the middle and rightmost pin.
To reduce the output voltage, insert a jumper to LK1 in the right position, so that the link is
between the middle and leftmost pin.
If the output voltage needs to be set to a different value (within the adjustment range) then
connect different value resistors in place of R1 (510kΩ) or R2 (0Ω) and connect the jumper
into the corresponding link setting.
Note: ensure that the down adjust resistor is not shorted when connecting a module that has a higher stated resistance in the
datasheet, as this could cause damage to the module.
5 Output
The Ag7300 will output 48V-58V and can deliver a continuous output current of 2.2A, for
up to 120W of continuous power, the peak output power may be reduced as a result of the
power source or operating conditions the module is operating in.
Output Power LED
LED2 illuminates when the module is outputting. This can be disabled by removing the
jumper link LK3, removing this link does not affect the power being supplied by the
Ag7300LPB.
