DC1850A-B

DC1850A-B is a LTC4366-2 very high voltage surge stopper with auto-retry demonstration board. Demonstration Circuit 1850A showcases the LTC®4366 high voltage surge stopper in a 28V vehicular application. DC1850A withstands inputs of up to 100VDC and input transients of up to 250V while maintaining the output at 43.1V. Reverse battery and errant inputs of up to –100VDC are blocked from reaching the output. DC1850A-B features auto-retry 9 seconds after tripping off in an overvoltage fault condition. The 9 second delay can be interrupted by pulsing the SHUTDOWN input.

• Input range operating 18V to 41V at TA = 25°C
• Output regulation range from 41V to 45.3V
