The TPS51313DRCT 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 TPS51313DRCT is available in a 3mm x 3mm, 10-pin DRC package (Green RoHS compliant and Pb free) and is specified between –10°C and 85°C.
