APPLICATION

Evaluating TEC controller TEC28V15A.

INTRODUCTION

This TEC controller, TEC28V15A, is designed to drive a TEC

at high efficiency for regulating the object temperature

precisely by controlling the direction and magnitude of the

current going through the TEC. It is powered by a DC voltage

between 9V to 28V and output current can go up to 15A

without using a heat sink.

This evaluation board, TEC28V15AEV1, is designed for

evaluating the controller TEC28V15A conveniently. It is

recommended to read this application note with the controller

datasheet which provides more detail information about the

specifications and application guidance for the controller.

The main purpose of using the evaluation board is to let the

controller drive a voltage configurable unbreakable dummy

laser diode on the board to emulate users’ actual expensive

laser diode with a programmable current. After making sure

the controller works properly and all the features and the setvalues

meet the requirements of the application, the users can

disconnect the dummy laser from the controller by turning a

switch and connect a real diode laser onto proper connections

of the board. The user will be able to set and monitor the

output current, read the controller’s temperature, monitor the

working status of the controller, etc.
