Additional preview pages of the SC2446 datasheet.

The SC2446 is a high-frequency dual synchronous stepdown switching power supply controller.

It provides outof-phase high-current output gate drives to all N-channel MOSFET power stages.

The SC2446 operates in synchronous continuous-conduction mode.

2-Phase synchronous continuous conduction mode for high efficiency step-down converters Out of phase operation for low input current ripples Output source and sink currents Fixed frequency peak current-mode control 75mV/-110mV maximum current sense voltage Synthesized MOSFET RDS(ON) current-sensing for low-cost.
