Digital Synchronous Buck Controller with Auto-Control® & SMBus™/PMBus™ - PV3101

The PV3101 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, with a single resistor, or through programming stored in the non-volatile memory (NVM). With Powervation’s Digital Stress Share (DSS) and PLL synchronization, multiple PV3101 devices may be used in parallel to increase the number of phases supporting the application’s load. PV3101 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. 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. PV3101 is a fully protected DC/DC solution that utilizes analog and digital functionality to maximize protection of the system. PV3101
