EVAL-LT8350-AZ

EVAL-LT8350-AZ is an evaluation circuit EVAL-LT8350-AZ a 40V synchronous buck-boost converter featuring the LT®8350. 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-LT8350-AZ runs at 350KHz switching frequency with spread spectrum frequency modulation (SSFM) disabled. When enabled, SSFM spreads the switching frequency of the LT8350 from fSW to fSW + 25% for reduced EMI emission. The LT8350 has an operating input voltage range of 3V to 40V. It has internal, synchronous 42V MOSFETs at buck-side and 20V MOSFETs at boost-side for high efficiency and small size. It has an adjustable switching frequency between 200KHz and 2MHz. The LT8350 can be synchronized to an external source, programmed with SSFM enabled for low EMI, or set to normal operation.
