Smallest TEC Power Drivers for Optical Modules
General Description
The MAX8520/MAX8521 are designed to drive thermoelectric coolers (TECs) in space-constrained optical modules. Both devices deliver ±1.5A output current and control the TEC current to eliminate harmful current surges. On-chip FETs minimize external ponents and high switching frequency reduces the size of external ponents. The MAX8520/MAX8521 operate from a single supply and bias the TEC between the outputs of two synchronous buck regulators. This operation allows for temperature control without “dead zones” or other nonlinearities at low...
