Description

The TPS51020DBT is a multi-function dual-synchronous Step-down Controller for notebook system power. The device is specifically designed for high performance, high efficiency applications where the loss associated with a current sense resistor is unacceptable. The device 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 one chip solution for all switching applications from 5V/3.3V supply to a complete DDR termination solution.
Selectable dual and DDR modes
Selectable fixed frequency voltage mode
