DESCRIPTION

The TPS51313 is an easy-to-use, fully integrated, synchronous buck converter for low voltage point-of-

load applications. It is designed to meet the NVIDIA™

OpenVreg Type 0 specifications, including the

package and footprint requirement. It supports 3-A

(maximum) of dc output current at output voltages

from 0.6 V to 3.3 V. The D-CAP2™ mode adaptive,

constant on-time control with 1-MHz switching

frequency allows a small footprint when designed

using all ceramic output capacitors and offers a low

external component count. The device also features

auto-skip function at light load condition, pre-biased

start-up and internally fixed soft-start time. When the

device is disabled, the output capacitor is discharged

through internal resistor. The TPS51313 is available

in a 3 mm x 3 mm, 10-pin DRC package (Green

RoHS compliant and Pb free) and is specified

between –10°C and 85°C.
