DC2081A-B

DC2081A-B demonstration circuit features the LTM4630EY-1, high efficiency, high density, dual 18A, switch mode step-down μModule® regulator with ±0.8% total DC output accuracy. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2081A-B is configured as dual-phase, single-output, which can deliver up to 36A maximum. With the help of external compensation, ±3% transient accuracy can be achieved with 25% load step. The board is designed with minimum components to demonstrate this high efficiency, high density μModule.
