A switching thermal regulator for efficiently and accurately regulating the temperature of an attached device, which includes a constant current supply, a thermistor, a signal processing amplifier, and a switching power supply. The thermistor, which is attached to the device to be regulated, senses the temperature of the device, and signals this temperature to the constant current supply, and signals this temperature to the signal processing amplifier which, in turn, signals this temperature to the switching power supply. Based on this voltage signal, the switching power supply adjusts the output voltage sent to a cooler, which allows the device to maintain a constant temperature.
