Dual-phase Single Or Two Output Synchronous Step-down Controller - Semtech Corporation

The SC2443 is a high-frequency dual synchronous Step-down switching power supply controller. It provides out-of-phase high-current output Gate drives to all N-Channel MOSFET power stages. The SC2443 operates in synchronous continuous-con- duction mode. Both phases are capable of maintaining regula- tion with sourcing or sinking load currents, making the SC2443 suitable for generating both VDDQ and the tracking VTT for DDR applications. The SC2443 employs fxed frequency peak current-mode con- trol for the ease of frequency compensation and fast transient response. The dual-phase Step-down controllers of the SC2443 CAN be used to produce two individually controlled and regulated out- puts or a single output with shared current in each phase. The Step-down controllers operate from an input of at least 4.7V and are capable of regulating outputs as low as 0.5V By Semtech Corporation
