Beschreibung
- DC1231A-A, Demonstration Circuit is a Dual Output, Dual Phase 5A Synchronous Buck Converter featuring the LTC3850EGN. The entire circuit, including the bulk output capacitors, fit within a 1.04 X 0.94 area on all layers. The package style for the LTC3850EGN is a 28-lead narrow plastic SSOP. The main features of the board include rail tracking, an internal 5V linear regulator for bias, RUN pins for each output and a PGOOD signal and a Mode selector that allow the converter to run in CCM, pulse skip or Burst Mode operation. Synchronization to an external clock is also possible through some minor component changes. The DC-1231A-A has an on-board sense resistor for current feedback
