POWER MANAGEMENT Description
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 the SC2446A suitable for generating both VDDQ and the tracking VTT for DDR applications.
The SC2446A employs fixed frequency peak currentmode control for the ease of frequency compensation and fast transient response.
The dual-phase step-down controllers of the SC2446A can be configur...
