Typical Application for SC2446 Dual-Phase Single or Two Output Synchronous Step-Down Controllers
参考设计 属于: Semtech
Typical Application for 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 with sourcing or sinking load currents, making the SC2446 suitable for generating both VDDQ and the tracking VTT for DDR applications
