Low-Voltage Point-of-Load (POL) Rails The TPS51313 is an easy-to-use, fully integrated,
synchronous buck converter for low voltage point-ofload applications. It is designed to meet the NVIDIAв„ў
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-CAP2в„ў 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 …
