Product Details

Demonstration circuit 1740A is a PolyPhase® synchronous buck converter featuring the LTC3880EUJ, a dual-phase current mode controller with PMBus interface and digital power system management functions. The DC1740A-A is a two chip 4-phase single-output configuration. The default output setting is VOUT0 = 1.2V/80A.

The DC1740A powers up to default settings and produces power based on configuration resistors or with non-volatile memory (NVM) settings without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter aspects of the LTC3880. To fully explore the extensive digital power management features of the parts, download the GUI software LTpowerPlay™ onto your PC and use LTC’s I2C/SMBus/PMBus Dongle DC1613A to connect to the board.
