A power controller monitors and controls the power supplies found in communication, networking, and storage equipment. Power supplies provide power to all of the components in a system, and in today's designs they have to do this to very tight specifications. These specifications include control of multiple energy current and voltage levels during startup and shutdown so that parts are powered on and off in the correct power sequence, and then monitoring during operation for handling of transients, relative voltage levels, and fault conditions.

Specifications like ATCA provide a single voltage from the backplane that can then require multiple DC-DC converters on each ATCA card. Tundra's Power Controllers are able to control and monitor multiple DC-DC converters. For example, a single Tundra Tsi257 can control up to six different power rails. Connect or cascade three Tsi257s together and you have integrated control for up to 18 power supplies. Control over power sequence and voltage level, as well as trimming or biasing, in-rush current and communication with a system controller, and a non-volatile fault log, are all capabilities delivered by the Tundra Power Controllers.
