Power Supply Controllers track up to 5 supplies.
Models LTC2921 and LTC2922 utilize N-channel MOSFETs to assure that multiple power supplies ramp up at same time and same rate, protecting ASICs, processors, and other circuitry from lock-up or more severe damage. Following successful ramp-up, remote sense switches allow regulators to close loop around MOSFETs and compensate for voltage drop. Adjustable electronic circuit breaker monitors primary...

Controller tracks and sequences power supply.
Model LTC2923, in tiny 10-lead MSOP package, controls power-supply start up and shut down by introducing currents into feedback nodes. By properly selecting resistors, supply can be configured to ramp-up and ramp-down together, with options for fixed voltage offsets, time delays, or different ramp rates. Unit allows additional supply to be controlled with FET for systems that require tracking of...
