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.
