Overview

Topology	Buck Converter
Input voltage	4.5-16 V
Output 1	3.3 V / 250 A

Description

Demonstration circuit 2638A-D is a high efficiency, high density, μModule regulator with 4.5V to 16V input range. The output voltage is adjustable from 0.5V to 3.3V, and it can supply 250A maximum load current. The demo board has five LTM4678 μModule® regulators, and the LTM4678 is a dual 25A or single 50A step-down regulator with PMBus power system management. Please see LTM4678 data sheet for more detailed information.DC2638A-D powers up to default settings and produce 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 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.
