Demonstration circuit 1936A is a high current, high efficiency, polyphase synchronous buck converter featuring the LTC3882EUJ, a dual output polyphase voltage mode controller. The LTC3882 has the PMBus interface and power system management functions.
The DC1936A uses 6mm × 6mm DrMOS as the power stage. The input range of this board is from 7V to 14V, and the output voltage can be programmed from 0.8V to 1.8V. The DC1936A provides two outputs, with each output capable of 1V/30A. The DC1936A has optional discrete driver (LTC4449EDCB) and MOSFET footprints for high input voltage applications up to 38V. The DC1936A also has an on-board dynamic load circuit, which makes it easy for the customer to evaluate the transient performances.
