Description
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-conduction mode. Both phases are capable of maintaining regulation with sourcing or sinking load currents, making the SC2443 suitable for generating both VDDQ and the tracking VTT for DDR applications.
Features
◆ Wide input voltage range: 4.7V to 16V
◆ 0.5V feedback voltage for low-voltage outputs
◆ Programmable frequency up to 1 MHz per phase
◆ 2-Phase synchronous continuous conduction mode for high efficiency step-down converters
◆ Out-of-phase operation for low input current ripples
◆ Output source and sink currents
◆ Fixed frequency peak current-mode control
◆ 75mV/-110mV maximum current sense voltage
◆ Inductor DCR current-sensing for low-cost applications
◆ Dual outputs or 2-phase single output operation
◆ Excellent current sharing between individual phases
◆ Individual soft-start, overload shutdown and enable
◆ External reference input for DDR applications
◆ External synchronization
◆ Industrial temperature range
◆ 4mm X 4mm X1mm 24-lead MLPQ package
Applications
◆ Telecommunication power supplies
◆ DDR memory power supplies
◆ Graphic power supplies
◆ Servers and base stations
