Topology	Buck Converter
Input voltage	4.5-16 V
Output 1	1.8 V / 400 A

Description

Demonstration circuit 2784A-C is a high efficiency, highdensity, μModule regulator with 4.5V to 16V input range. The output voltage is adjustable from 0.5V to 1.8V and it can supply 400A maximum load current. The demo board has four LTM®4700 μModule regulators, which is a dual 50A or single 100A step-down regulator with digital power system management. Please see LTM4700 data sheet for more detailed information.DC2784A-C powers up to default settings and producespower based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download All registered trademarks and trademarks are the property of their respective owners. BOARD PHOTO the GUI software LTpowerPlay® onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.
