Ultra-Small, VR12.0 / VR12.5 Digital Synchronous Buck Controller with Auto-Control® & SMBus™ / PMBus™ - PV3103

The PV3103 is a digital synchronous buck controller with adaptive loop compensation, for point-of-load (POL) applications. The PV3103 complies with the Serial VID (SVID) portion of Intel’s VR12 specification in order to support Intel-based memory, graphics and similar applications. Through SVID, the CPU can dynamically control the output voltage, slew rates, power states, as well as monitor the VR controller for telemetry purposes. In parallel to SVID, the PV3103 also supports a set of PMBus commands, allowing a BMC in a server application to configure, control and monitor the VR controller.

PV3103 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.

The digital functionality of this VR controller allows system telemetry (remote measurement and reporting) of current, voltage, and temperature information through its serial interfaces. Additionally, to maximize system performance and reliability, the IC provides temperature correction/compensation of several parameters. PV3103 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize system protection.
