SC2446A Datasheet (Semtech Corporation) - Dual-Phase Single or Two Output Synchronous Step-Down Controller

SC2446A, Dual-Phase Single or Two Output Synchronous Step-Down Controller

The SC2446A is a high-frequency dual synchronous stepdown switching power supply controller.

It provides outof-phase output gate signals.

The SC2446A operates in synchronous continuous-conduction mode.

Both phases are capable of maintaining regulation with sourcing or sinking load currents, making t
