SC2441A controllers equivalent, 1.8v to 20v input 2-phase synchronous step-down controllers.
2-Phase Synchronous Step-down Controllers u 2-Phase Synchronous Continuous Conduction Mode u Out of Phase Operation for Low Input Current Ripple u Operates up to 1MHz Per.
where a low-voltage input (<3.3V) is to be stepped down for lower voltage logic, yet the input is too low to drive power.
