Analog Devices LT8350S | Demoboard EVAL-LT8350S-AZ

Description

The EVAL-LT8350S-AZ Evaluation board is a 40V synchronous buck-boost converter featuring the LT®8350S. It drives up to 2.5A load at 12V output when VIN is between 9V and 40V and will run down to 3VIN with reduced output current. EVAL-LT8350S-AZ runs at 350kHz switching frequency with spread spectrum frequency modulation (SSFM) disabled. When enabled, SSFM spreads the switching frequency of the LT8350S from fSW to fSW + 25% for a reduced electromagnetic interference (EMI) emission.
