PV3012 delivers voltage precision of ±0.5% over line, load, and the full -40°C to 125°C temperature range. The converter’s output can be configured from 0.6 V to 5.5 V using PMBus™ commands or with an external resistor to access standard and DOSA set-point tables. Phases may be automatically added or removed as the load varies, maximizing efficiency over the load range. Additionally, with Powervation’s Digital Stress Share (DSS) single-wire bus, multiple PV3012 devices can be connected in parallel to securely drive high current multi-phase loads.
PV3012 is a system on chip solution based on a lean DSP/RISC dual-core architecture with a precision data acquisition engine running advanced Auto-Control algorithms in firmware – the result is a high performance and flexible voltage regulator equipped to manage the complex power needs of today’s system designers. PV3012 is designed to work with all leading driver and FET solutions to allow the designer maximum flexibility. This feature rich controller provides advanced configuration capabilities and leading protection features while providing a highly integrated solution which reduces component count.
This full suite PMBus compliant controller uses full differential measurements and an 11 bit ADC to provide precision system telemetry of current, voltage, and temperature information, as well as comprehensive fault and warning reporting over SMBus interface. Additionally, to enhance system performance and reliability, PV3012 delivers advanced digitally mapped temperature compensation of key parameters which enables current measurement precision of 3% over the full load range. The PV3012’s anti-fuse based non-volatile memory (NVM) is specified from -40°C to 125°C (20 year data retention rating) making the device suited to datacentres and base station applications. Users can configure and store up to eight configuration tables in NVM, which enables single resistor selection of one of eight device/application profiles, with considerable supply chain benefit.
