APPLICATIONS Notebook Computers System Bus and I/O DDR I or DDR II Termination
DESCRIPTIONThe TPS51020 is a multi-function dual-
synchronous step-down controller for notebook
system power. The part is specifically designed
for high performance, high efficiency applications
where the loss associated with a current sense
resistor is unacceptable. The TPS51020 utilizes
feed forward voltage mode control to attain high
efficiency without sacrificing line response.
Efficiency at light load conditions can be
maintained high as well by incorporating autoskip
operation. A selectable, Suspend to RAM (STR)
supported, DDR option provides a one chip
solution for all switching applications from
5-V/3.3-V supply to a complete DDR termination
solution.
