Temperature Controller

A proportional temperature controller capable of 40 watts output was designed to regulate the processor temperature.  The controller uses 12V from the computer power supply and outputs a variable 0-9 volt DC to the thermoelectric device.  The processor temperature control is based on a TL598 Pulse Width Modulator.  A schematic of the controller, sectioned into three main parts, is shown below.
