MAX1978ETM+ Product Details
The MAX1978ETM+ is an integrated temperature controller for peltier thermoelectric cooler (TEC) modules in 48 pin TQFN package. On-chip power FETs and thermal control loop circuitry minimize external components while maintaining high efficiency. Selectable 500KHz/1MHz switching frequency and unique ripple cancellation scheme optimize component size and efficiency while reducing noise. Switching speed of internal MOSFET is optimized to reduce noise and EMI. The MAX1978ETM+ operates from single supply and provides bipolar ±3A output by biasing TEC between outputs of two synchronous buck regulators. A chopper stabilized instrumentation amplifier and high precision integrator amplifier are supplied to create a proportional integral (PI) or proportional integral derivative (PID) controller. The MAX1978ETM+ is used in fibre optic laser modules, WDM, DWDM laser diode temperature control, fibre optic network equipment, EDFA optical amplifiers, ATE and telecom fibre interfaces.
Feature
