1.8V to 20V Input 2-Phase Synchronous Step-down Controllers with Step-up Converter

The SC2441A is a programmable frequency dual independent or dual/multiple phase single output peak current-mode step-down switching regulator controller. It is capable of operating from 1.8V to 20V input. A 0.6A step-up converter in the SC2441A generates an auxiliary gate drive supply when VIN is be 2-Phase Synchronous Step-down Controllers\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t·2-Phase Synchronous Continuous Conduction Mode\n\t\t\t\t\t\t\t\t\t\t\t·Out of Phase Operation for Low Input Current Ripple\n\t\t\t\t\t\t\t\t\t\t\t·Operates up to 1MHz Per Channel\n\t\t\t\t\t\t\t\t\t\t\t·Excellent Cur;
