TPS54872, Tracking/Termination Synchronous PWM Switcher

www.ti.com 6,4 mm x 9,7 mm TPS54872 SLVS436C * JULY 2002 * REVISED FEBRUARY 2005 8ĆA OUTPUT, 4ĆV TO 6ĆV INPUT TRACKING/TERMINATION.
As a member of the SWIFT family of dc/dc regulators, the TPS54872 low-input voltage high-output current synchronous-buck PWM converter integrates all.

Features

* D Tracks Externally Applied Reference Voltage D 30-mΩ MOSFET Switches for High Efficiency at 8-A Continuous Output Source or Sink Current D 6% to 90% VI Output Tracking Range D Wide PWM Frequency: Fixed 350 kHz or Adjustable 280 kHz to 700 kHz D Load Protected by Peak Current Limit and Thermal Shutd

Applications

* D DDR Memory Termination Voltage D Active Termination of GTL and SSTL High-Speed Logic Families D DAC Controlled High Current Output Stage D Precision Point of Load Power Supply The TPS54872 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD package, which eliminates bulky heatsinks.
