Monitor IC optimizes board energy consumption

A four-channel PMBus digital power-system manager IC, the LTC2975 from Linear Technology, performs current, power, and energy monitoring of the intermediate-bus input to point-of-load (POL) converters. The device relieves the host of burdensome computation and poling by providing the energy consumed, reported in joules, and the elapsed time through a PMBus interface. When combined with its digital measureme ...
