Description
The SC486 is a combination switching regulator and linear source/sink regulator intended for DDR1/2/3 memory systems. The switching regulator is used 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 linear source/sink regulator is used to generate the memory termination voltage, VTT, with the ability to source and sink a 3A peak current.
Features
DDR1, DDR2 and DDR3 compatible
Constant on-time controller for fast dynamic response on VDDQ
Programmable VDDQ range - 1.5V to 3V
1 Internal Reference (2 System Accuracy)
Resistor programmable on time for VDDQ
VCCA/VDDP range = 4.5V to 5.5V
VBAT range = 2.5V to 25V
VDDQ DC current sense using low-side RDS(ON) sensing or external RSENSE in series with low-side FET
Cycle-by-cycle current limit for VDDQ
Digital soft-start for VDDQ
Combined EN and PSAVE pin for VDDQ
Over-voltage/under-voltage fault protection for both outputs and PGD output (VDDQ only)
Separate VCCA and VDDP supplies
VTT/REF range = 0.75V – 1.5V
VTT source/sink 3A peak
Internal resistor divider for VTT/REF
VTT is high impedance in S3
VDDQ, VTT and REF are actively discharged in S4/S5
24-pin MLPQ (4 x 4mm) Lead-free package, fully WEEE and RoHS compliant
Applications
Notebook computers
CPU I/O supplies
Handheld terminals and PDAs
LCD monitors
Network power supplies
