Analog Devices Inc. DC2407A Demo Circuit for LT8650S
Analog Devices DC2407A Demo Circuit is a demonstration and evaluation board featuring a typical application circuit based on the LT8650S Synchronous Step-DownSilent Switcher 2. The demonstration circuit offers 5V and 3.3V outputs. Each output can source up to 4A continuous current at the same time. The SYNC pin on the Demo Circuit Board is grounded by default for low ripple Burst Mode® operation. Jumper adjustments allow o synchronizing to to an external clock and enabling spread spectrum mode. The Demo Circuit 2407A runs at 2MHz to minimize solution size. The efficiency is 92%. The IC temperature rise is less than 50°C when both channels run at full load, 4A each, at 2MHz.Specifications
