Renesas' Simple Digital Power Modules provide reliable power for FPGAs, ASICs, DSPs, and microprocessors. They leverage the advantages of a digitally-controlled power supply while eliminating the need to store operating parameters in non-volatile memory. Configuration is instead performed through pin-strap resistor selection, while a PMBus interface is also available for run-time configuration and telemetry.

Key Features

  • Renesas’ proprietary ChargeMode™ control architecture responds to a transient load step in a single switching cycle, reducing output capacitance, cost and board space. It also eliminates external compensation components and accommodates aging of external passive components.
  • Advanced HDA packaging technology provides excellent thermal performance over a wide range of operating temperatures without the need for airflow or a heat sink.
  • Online design support tools, including PowerNavigator™, PowerCompass™ and SIMPLIS models, lead to fast time-to-market powertrain development and optimization.
