DC2481B-B Demo Circuit for LTM4677/4650 Regulators

Analog Devices Inc. DC2481B-B Demo Circuit is for the demonstration of the LTM4677/4650 high-efficiency, high-density µModule^® regulators with a 4.5V to 15V voltage input range. This circuit offers 0.6V to 1.8V adjustable output voltage and supplies 86A maximum load current. The DC3481B-B demonstration circuit features LTM4677 and LTM4650 µModule regulators. The LTM4677 is a dual 18A or single 36A step-down regulator with PMBus power system management, and the LTM4650 is a dual 25A or single 50A step-down regulator. The DC2481B-B powers up to default settings and produces power based on configuration resistors without the need for any serial bus communication. This allows for easy evaluation of the DC/DC converters.
