SC2446: Dual-Phase Single Or Two-Output Synchronous Step-Down Controller | Semtech

The SC2446 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-chan- nel MOSFET power stages. The SC2446 operates in syn- chronous continuous-conduction mode. Both phases are capable of maintaining regulation with sourcing or sink- ing load currents, making the SC2446 suitable for gen- erating both V and the tracking V for DDR applica- DDQ TT tions. The SC2446 employs fixed frequency peak current-mode control for the ease of frequency compensation and fast transient response. The dual-phase Step-down controllers of the SC2446 CAN be configured to provide two individually controlled and regulated outputs 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 out- puts as low as 0.5V By Semtech Corporation
