The MAX8520ETP+T from Analog Devices (formerly Maxim Integrated) is a high-efficiency, switch-mode power driver designed for thermoelectric coolers (TECs) in space-constrained optical modules. It provides ±1.5A of output current, precisely controlling TEC current to prevent harmful surges. The device features on-chip power MOSFETs, minimizing external component count and enabling a low-profile design.
This TEC driver operates from a single 3V to 5.5V supply, biasing the TEC between two synchronous buck regulators. This architecture ensures accurate temperature control without dead zones or nonlinearities at low currents, preventing hunting. The MAX8520ETP+T offers individually adjustable heating and cooling current limits with 5% accuracy, and a 2% accurate TEC voltage limit for enhanced reliability.
With a switching frequency up to 1MHz, the device allows for smaller external components. It is housed in a 20-TQFN (5x5mm) package suitable for surface mounting. The MAX8520ETP+T is ideal for applications such as SFF/SFP modules, fiber optic laser modules, and other fiber optic network equipment requiring precise temperature stabilization.
