Analog Devices Inc. EVAL-LT8337-AZ/EVAL-LT8337-1-AZ Evaluation Board
Analog Devices Inc. EVAL-LT8337-AZ/EVAL-LT8337-1-AZ Evaluation Boards are a demonstration platform for the LT8337 or LT8337-1 Synchronous Step-Up Silent Switcher®. The LT8337/LT8337-1 is a low IQ, synchronous step-up DC-DC converter. It features Silent Switcher architecture and optional Spread Spectrum Frequency Modulation (SSFM) to minimize EMI emissions while delivering high efficiencies at high switching frequencies.
The Analog Devices Inc. EVAL-LT8337-AZ/EVAL-LT8337-1-AZ Evaluation Boards feature a pre-mounted LT8337 or LT8337-1 in an LQFN-16 package. The Evaluation Boards provide an example application circuit providing a 12V output from 4.5V to 12.0V input. When VIN goes above the 12V output regulation setpoint, the LT8337/LT8337-1 smoothly transitions between regulation and PassThru™ mode. The Evaluation Boards feature jumpers to select Pulse Skip, Pulse Skip + SSFM, Burst, Burst + SSFM, or Sync modes.
