Input voltage48 V
Output 112 V / 2 A

Description

Demonstration circuit SCP-LT8362-S-EVALZ features the LT8362 in a SEPIC configuration. It operates with a switching frequency of 2MHz and has an output voltage of 12V.Like 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-FILTER-EVALZ SCP-THRUBRD-EVALZ SCP-1X2BKOUT-EVALZ SCP-1X5BKOUT-EVALZ SCP-5X1-EVALZ To properly evaluate SCP series demo boards, you will need the SCP Configurator companion software. SCP Configurator can help you choose the right board and topology for your design.Note that the Demo Manual does not cover details important to the operation and configuration regarding the LT8362. Please refer to the LT8362 datasheet for a complete description of the part.
