Ultra-Small, Digital Synchronous Buck Controller with Auto-Control®, and SMBus™ and 3-Bit PVID Interfaces - PV3114

The PV3114 is a digital synchronous buck controller with adaptive loop compensation, for point-of-load (POL) applications. The output can supply 0.6 V to 5.5 V, and can be configured and controlled via PMBus or through programming stored in the non-volatile memory (NVM). In addition to the SMBus interface, PV3114 provides a 3-bit parallel VID interface with a mapping from 0.85 V to 1.0 V in 25 mV steps, and 1.05 V. PV3114 uses Powervation’s proprietary adaptive digital control loop, Auto-Control, which adapts on a cycle-by-cycle basis, and provides active loop compensation to stabilize the control loop as the phases are added and removed. The digital functionality of this PMBus power converter controller allows system telemetry (remote measurement and reporting) of current, voltage, and temperature information. Additionally, to maximize system performance and reliability, the IC provides temperature correction/compensation of several parameters. PV3114 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize protection of the system. PV3114
