Analog Devices Inc. EVAL-LT8350S-AZ Evaluation Board
Analog Devices EVAL-LT8350S-AZ Evaluation Board is based on the LT8350S 40V synchronous buck-boost converter. The LT8350S has an operating input voltage range of 3V to 40V. The device has internal, synchronous 42V MOSFETs on the Buck side and 20V on the Boost side for high efficiency in a small size.
The ADI EVAL-LT8350S-AZ drives up to 2.5A load at 12V output when VIN is between 9V and 40V and will run down to 3VIN with decreased output current. The EVAL-LT8350S-AZ operates at a 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.
