Overview
Product Details
Demonstration circuit 1940A is a low quiescent current, synchronous buck converter featuring the LTC3891EUDC. This demo board converts a 16V to 60V voltage to a 12V at 15A output. The main features of this board include an internal LDO for gate drive power from VIN or EXTVCC, RUN and PGOOD pins, a mode selector that allows the converter to run in constant current mode (CCM), pulse-skipping or Burst Mode® operation, and selectable current limit. The DC1940A supports an adjustable output voltage, soft-start and tracking. The wide input voltage range of 16V to 60V is suitable for double battery automotive and distributed DC power systems where low quiescent current is important.
