This is the manual for DC2244A provided by Linear Technology Corporation.
This manual provides instructions for setting up and operating the DC2244A demonstration circuit, which includes the LTM8049 dual SEPIC or inverting µModule DC/DC converter. The board is configured for two independent DC/DC converters with +12.0V and -12.0V outputs from an input voltage up to 20V. Switching frequencies are set at 1MHz, with frequency foldback for protection during faults or overloads. The manual includes a quick start procedure, performance specifications, parts list, and schematic diagrams for modification and paralleling configurations. This manual is written in Chinese.
