19-2490; Rev 0; 7/02 EVAALVUAAILTAIOBNLEKIT Integrated Temperature Controllers for Peltier Modules MAX1978/MAX1979 General Description The MAX1978/MAX1979 are the smallest, safest, most accurate plete single-chip temperature controllers for Peltier thermoelectric cooler (TEC) modules. On-chip power FETs and thermal control-loop circuitry minimize external ponents while maintaining high efficiency. Selectable 500kHz/1MHz switching frequency and a unique ripple-cancellation scheme optimize ponent size and efficiency while reducing noise. Switching speeds of internal MOSFETs are optimized to reduce noise and EMI. An ultralow-drift chopper amplifier maintains ±0.001°C temperature...
