Digital Dual-Phase Synchronous Buck Controller with Auto-Control®, and SMB™ and 3-Bit PVID Interfaces - PV3204

The PV3204 is a dual phase 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, PV3204 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.

This controller may be used in single or dual phase mode. When used in dual phase mode, phases may be added or removed as the load varies, so that efficiency is maximized over the load range. Additionally, the outputs of the phases are interleaved so that the effective switching frequency at the output is doubled. PV3204 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. PV3204 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize protection of the system.
