BOARD DESCRIPTION
The TEC controller evaluation board TECEV104 is consisted
of a complete tuning and application circuit for driving a TEC.
It can set the output voltage limit, tune the compensation
network, set internal operating temperature point, and has an
LED for indicating the temperature status of the controller,
and has numerous connection pads for making connections
with external components and instruments.
Its photo is shown in Figure 1. The TEC controller module is
located in the center of the TECEV104 Evaluation Board. The
voltages of all its pins can be measured directly by probing the
vias on the left and right side of the module sockets which are
connected directly with pins of the electronic module. Some of
the pins are also connected to the soldering pads with two vias
on the edges of the board. The names of all these nodes are
marked on the board.
The silkscreen layer of the evaluation board is shown in Figure
2 with other top layers, including top silkscreen, top copper,
top solder mask, and multilayer (vias). Figure 3 only shows
the image of top silkscreen layer. There is no component in the
bottom side of the board, so that there is no bottom silkscreen
layer image.
