DC2674A

Demonstration circuit 2674A is a 140V high efficiency switching surge stopper featuring the LTC®7862. The board operates from an I/P voltage range of 8 to 140V and provides 8 to 34V O/P from 0 to 10A. Its O/P voltage is programmed to be clamped at 34V (typical) with a minimum ride-through duration of 500ms. Its O/P current is limited to protect against output short-circuit faults. A soft-start feature is utilized to control its O/P voltage slew rate at start-up and input voltage transients. This feature reduces current surge and O/P voltage overshoot. The demonstration board is able to achieve low insertion drop by utilizing the low RDS(ON) N-channel MOSFETs and low DCR inductor. This board also includes optional reverse polarity protection circuit which protects the down stream loads up to -40V. The demonstration circuit is suitable for a wide range of automotive, industrial and telecom applications.
