SC488MLTRT General Description

Description The SC488 is a combination switching regulator and linear source/sink regulator intended for DDR1/2 memory systems. The purpose of the switching regulator is to generate the supply voltage, VDDQ, for the memory system. It is a pseudo-fixed frequency constant on-time controller designed for high efficiency, superior DC accuracy, and fast transient response. The purpose of the linear source/sink regulator is to generate the memory termination voltage, VTT, with the ability to source and sink 2.8A peak currents.Features ♦ Constant On-Time Controller for Fast Dynamic Response on VDDQ ♦ DDR1/DDR2/DDR3 Compatible ♦ VDDQ = Fixed 1.8V or 2.5V, or Adjustable From 1.5V to 3.0V ♦ 1.5% Internal Reference (2.5% System Accuracy) ♦ Resistor Programmable On-Time for VDDQ ♦ VCCA/VDDP Range = 4.5V to 5.5V ♦ VIN Range = 2.5V to 25V ♦ VDDQ DC Current Sense Using Low-Side RDS(ON) Sensing ♦ External RSENSE in Series with Low-Side FET ♦ Cycle-by-Cycle Current Limit for VDDQ ♦ Digital Soft-Start for VDDQ ♦ Analog Soft-Start for VTT/REF ♦ Smart Over-Voltage VDDQ Protection ♦ Combined EN and PSAVE Pin for VDDQ ♦ Over-Voltage/Under-Voltage Fault Protection ♦ Power Good Output ♦ Separate VCCA and VDDP Supplies ♦ VTT/REF Range = 0.75V – 1.5V ♦ VTT Source/Sink 2.8A Peak ♦ Internal Resistor Divider for VTT/REF ♦ VTT is High Impedance in S3 ♦ VDDQ, VTT, REF are Actively Discharged in S4/S5 ♦ 24 Lead MLPQ (4x4 mm) Lead-Free Package ♦ Product Is Fully WEEE and RoHS CompliantApplications ♦ Notebook Computers ♦ CPU I/O Supplies ♦ Handheld Terminals and PDAs ♦ LCD Monitors ♦ Network Power Supplies
