DC1811B-B

DC1811B-B is a LTM4676A dual step-down µModule regulator with PMBus digital power system management demonstration board. Demonstration circuit 1811B-B is a dual-output, high efficiency, high density, µModule® regulator with 4.5V to 26.5V input range. Each output can supply 13A maximum load current. The demo board has a LTM®4676A µModule regulator, which is a dual 13A or single 26A step-down regulator with PMBus power system management. The DC1811B-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.

• 86.3% typical efficiency at VIN = 12V, VOUT = 1.8V, IOUT = 13A, TA = 25°C
• 500KHz default switching frequency at TA = 25°C
