DC2106B-B: 1V @ 130A, 4.5 ~ 16V in, Buck


Demonstration circuit 2106B-B is a high efficiency, high density, µModule regulator with 4.5V to 16V input range. The output voltage is adjustable from 0.5V to 1.8V, and it can supply 130A maximum load current. The demo board has 1× LTM®4676A and 3× LTM4630 µModule regulators. The LTM4676A is a dual 13A or single 26A step-down regulator with PMBus power system management, and the LTM4630 is a dual 18A or single 36A step-down regulator.

Please see LTM4676A and LTM4630 data sheets for more detailed information.DC2106B-B powers up to default settings and produces power 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 the GUI software LTpowerPlay™ onto your PC and use LTC'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, and view telemetry of voltage, current, temperature and fault status.
