Digital Power (Powervation)

ROHM delivers energy-efficient solutions for power systems used in Networking, Storage and Computing applications. The company’s digital power IC technology brings fully automatic adaptive control to DC/DC conversion for the first time in a reliable package that reduces design complexity and cost, increases power-supply performance and accelerates time to market.


Digital DC/DC Controllers

The Powervation digital architecture for digital power management solutions is a multi-processor system on chip (SoC) which consist of an ultra-lean proprietary dual core (DSP and RISC processor), both RAM and non-volatile memory (NVM), power conversion blocks, SMBus serial interface and DSS®, analog-to-digital converters (ADC) and digital-to-analog converter (DAC), and timing sources (oscillator and phase lock loop).

This mixed-signal digital power management controller, with its onboard processing power and memory, combines power management and mixed-signal functions, and is able to store and run computational algorithms in firmware. The architecture also allows the digital controllers to be extremely flexible in their configuration, and for users to easily store (in memory) a large number of parameters used in the design of switch mode power supplies – thus maximizing configuration flexibility while eliminating external components.
