Powervation, an Ireland-based developer of adaptive digital power ICs has announced a single phase digital DC/DC controller featuring the company’s Auto-Control adaptive loop compensation technology.

The PV3101 uses a proprietary DSP/RISC dual-core architecture with a precision data acquisition engine running advanced control and power management algorithms in firmware.  

At the heart of the design is an adaptive loop compensation algorithm which provides real-time autonomous compensation and is able to modulate the converter’s bandwidth on a cycle-by-cycle basis to optimise performance. 

It uses full differential voltage, current, and temperature measurements and an 11 bit ADC to provide precision measurement (e.g., ±3% IOUT accuracy over temperature), tight control (e.g., ±0.5% VOUT over line, load, and temperature), and real-time reporting of telemetry information for key power supply parameters.

Has added features to increase the digital DC/DC controller's light-load efficiency. 

The controller supports a diode emulation mode that triggers once the converter enters DCM operation, thus preventing the low-side FET from sinking current when the inductor current ramps down to zero. 

There is also a pulse skipping mode that reduces high-side FET switching losses by eliminating unneeded switching cycles, while still maintaining tight output regulation.  

RoHS compliant, the PV3101 is sampling in 32-lead QFN packaging.
