Analog Devices Inc. LTC2971 2-Channel Power System Managers
Analog Devices Inc. LTC2971 2-Channel Power System Managers are used to sequence, trim (servo), margin, supervise, manage faults, and provide telemetry and log faults. These power system managers use a proprietary soft-connect algorithm to minimize supply disturbances. The LTC2971 2-channel managers monitor 0V to 60V input voltage, input current within 1%, and accumulate energy. These managers manage outputs from -60V to 60V and margin or trim to within 0.25%. Typical applications include computers and network servers, industrial test and measurement, high reliability systems, and video and medical imaging.Features
