DESCRIPON

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
