The device is a FET-integrated synchronous buck regulator designed mainly for DDR termination. It can provide a regulated output at ½ VDDQ with bothsink and source capability. The device employs D-CAP+ mode operation that provides ease of use, low external component count and fast transient response. The device canalso be used for other point-of-load (POL) regulation applications requiring up to 6 A. Inaddition, the device supports full, 6-A, output sinking current capability with tight voltageregulation.

The device features two switching frequency settings (600 kHz and 1 MHz), integrateddroop support, external tracking capability, pre-bias startup, output soft discharge, integratedbootstrap switch, power good function, V5IN pin UVLO protection, and supports both ceramic andSP/POSCAP capacitors. It supports input voltages up to 6.0 V, and output voltages adjustable from to 2.0 V.

The device is available in the 3.5 mm × 4 mm, 20-pin, VQFNpackage (Green RoHs compliant and Pb free) with TI proprietary Integrated MOSFET and packaging technology and is specified from –40°C to 85°C.

For all available packages, see the orderable addendum at the end of the data sheet.
