Demonstration circuit SCP-LT1956-BEVALZ is a 48V, 1A load current, monolithic step-down DC/DC switching converter with a wide input range for applications which require higher input voltage. As all boards in the signal chain power series, this board is designed to be easily plugged into other SCP boards to form a complete signal chain power system, enabling fast evaluation of low power signal chains. To evaluate this board, some universal SCP hardware is required, namely: SCP-INPUT-EVALZ, SCP-OUTPUT-EVALZ, SCP-1X5BKOUT-EVALZ, SCP-THRUBRD-EVALZ, SCP-FILTER-EVALZ, SCP-1X2BKOUT-EVALZ and SCP-5X1-EVALZ.
