Description
- DC2481B-A, Demonstration Circuit is a high efficiency, high density, Module regulator with 4.5V to 15V input range. The output voltage is adjustable from 0.6V to 1.8V, and it can supply 86A maximum load current. The demo board has 1x LTM4677 and 1x LTM4650 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-A 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
