SC2446 Datasheet (Semtech Corporation) - Dual-Phase Single or Two Output Synchronous Step-Down Controller

SC2446, Dual-Phase Single or Two Output Synchronous Step-Down Controller

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.

Both phases are capable of maintaining regulation w
