Texas Instruments LM5155EVM-SEPIC Controller Evaluation Module
Texas Instruments LM5155EVM-SEPIC Controller Evaluation Module (EVM) showcases the features and performance of the LM5155 as a wide input non-synchronous SEPIC controller. The standard configuration is designed to provide a regulated output of 12V at up to 2A from an input of 3V to 42V, switching at 2.2MHz. By replacing the IC, the Texas Instruments LM5155EVM-SEPIC can also demonstrate the performance of the LM51551-Q1, LM5155, and LM51551.
