Demonstration circuit 1811B-A 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 LTM4676 μModule regulator, which is a dual 13A or single 26A step-down regulator with PMBus power system management. Please see LTM4676 data sheet for more detailed information.
Demonstration circuit 2269A-A is a dual-output, high efficiency, high density, μModule® supply on a small 1.5" × 1.2" PCB board with 4.5V to 26.5V input range. Each output can supply 13A maximum load current. The demo board has a LTM4676 μModule regulator, which is a dual 13A or single 26A step-down regulator with PMBus power system management. The DC2269A can be easily inserted to an edge connector for testing and debugging. It has an optional input filter inductor (L1) to further reduce input ripple EMI noise.
Demonstration circuit 2087A is a single-output, high efficiency, high density, μModule® regulator with 4.5V to 16V input range. It can supply 26A maximum load current. The demo board has a LTM4676 μModule regulator, which is a dual 13A or single 26A step-down regulator with PMBus power system management. Please see LTM4676 data sheet for more detailed information.
