EVAL-LT7826-AZ Evaluation Board User Guide
Evaluation board for the LT7826 switched capacitor converter, supporting 2:1 divider or 1:2 doubler modes up to 17V input and 8A output current.
Overview
The EVAL-LT7826-AZ is an evaluation circuit for the LT7826 monolithic switched capacitor DC/DC converter. This inductor-less converter operates as either a 2:1 voltage divider or a 1:2 voltage doubler, delivering up to 8A of output current. It supports a VHIGH range of 3.4V to 17V and a VLOW range of 1.7V to 8.5V at a fixed 500kHz switching frequency. The board features integrated bootstrap diodes, programmable undervoltage lockout (UVLO), and protection against overcurrent and overtemperature. It includes a pre-balance mode for no-load startup and supports frequency synchronization for parallel or interleaving operations.
