DC2150A-C

DC2150A-C demonstration circuit uses the LTC®4366-2 and LT4363-2 surge stoppers to satisfy MIL-STD-1275D. This specification, created by United States Department of Défense, sets down requirements of electrical systems powered from a military vehicle’s 28V power supply. DC2150A’s O/P voltage is limited to 44V when faced with MIL-STD-1275D’s onerous surge, spike and ripple conditions. In most circumstances, satisfying MIL-STD1275D is as simple as placing this circuit in front of 44V tolerant device. The default version, DC2150A-C, provides min of 4A to O/P in all conditions except ±7V ripple condition (14Vpeak-to-peak). During the ripple condition, DC2150A-C provides min of 2.8A to load. Exceeding 2.8A during the input ripple condition may cause DC2150A-C to timeout and shut off in less than MIL-STD-1275D’s one minute ripple ride-through requirement. DC2150A’s MOSFETs are protected against output overloads by current limiting.

• Input supply range from 8 to 40V (operating) at TA = 25°C
• Output regulation voltage range from 41 to 46V at TA = 25°C
• 5A current limit TA = 25°C
