General Description

The SC2441 is a high-frequency triple output switching regulator controller.

It consists of a dual out-of-phase synchronous step-down PWM controller with high-current output gate drives and a 1.7A integrated step-up switching regulator.

The dual-phase step-down controller of the SC2441 can be configured to provide two individually controlled and regulated outputs or a single output with shared current in each phase.
