SC2447 Datasheet (Semtech Corporation) - Dual-Phase Single or Two Output Synchronous Step-Down Controller

SC2447, Dual-Phase Single or Two Output Synchronous Step-Down Controller

The SC2447 is a versatile high-frequency dual phase PWM step-down controller optimized for Philips and Renesas DrMOSTM.

Both phases are capable of sourcing or sinking load currents, making the SC2447 suitable for networking system power and DDR applications.

The SC2447 employs fixed frequency, conti
