I not giving them any thing there I just tested about 100 of them as to there rating
and did a lot of digging on the net
TND329
5 W Cellular Phone CCCV
(Constant Current Constant
Voltage) AC-DC Adapter
better charger like the smart phones and iphone use these in them and there
Not this same chip but one like it.
This reference document describes a built-and-tested,
GreenPoint solution for a cellular phone Constant Current
Constant Voltage (CCCV) AC-DC adapter. This design is
intended for isolated, low power, universal input off-line
applications where a constant current/constant voltage
output (CCCV) is required for charging NiCd, NiMH,
Lithium-ion or similar batteries. Typical applications would
include cell phone chargers or cordless phone chargers.
Back to the Op you may be able to use the supply you posted if like I said they fit the happy spot of 7 to 12 volts but may need to add a regulator and filtering
See I have a bunch of these old ones and new ones and got to wondering why some of the old one where no way near there rated voltage and the newer one where dead on 5 volts and I got my kids two new phones so we had 4 of the same
chargers that open the door to cut one open and have a look and as I figured
they have CCCV
So draythomp test it for output voltage and see what it is you may be able to use
the E-Bay supply but I have to say one thing if the output is 350mA and it's 2 watts it's only good for about 5.7 volts at that load
