Nov 05, 2003 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 supply for over-current faults. Threshold accuracy is ±1%.
