Product Overview

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
  • Advanced power good logic monitors both channels
  • Selectable autoskip mode
  • Integrated boot strap diodes
  • 180° Phase shift between channels
  • 5V, 60mA Integrated regulator
  • Input feed forward control
  • 1% Internal 0.85V reference
  • RDS(on) overcurrent detection (4200 ppm/°C)
  • Integrated OVP, UVP and power good timers
  • Green product and no Sb/Br
