Digital power

Design using any power topology while exceeding performance standards and using fewer development resources to pass power design specifications.

Flexibility, efficiency and integration for your power design needs

Digital Power is a way to control a power supply where the main control loops are typically regulated in digital (current and voltage). This brings flexibility through software to the system implementation of our Functional Safety-Compliant devices, including monitoring, communication, supervision and security layers. Digital power is at the heart of electric vehicle, solar inverter, energy infrastruture, server and telecom power designs. These applications require advanced control methods and complex topologies, such as multiphase converter, totem-pole PFC, bidirectional or DC/DC converters.

C2000 MCUs address the growing need for high efficiency, smaller form factor and adaptabilityin digitally controlled power electronic converters.

Regulatory standards mandate power factor correction (PFC) systems to reduce burden on distribution systems. PFC stages also improve downstream conversion efficiency. Modern converters need isolated communications plus advanced yet flexible topologies for maximum efficiency. Digital power solutions improve total harmonic distortion and reduce EMI in the PFC stage.
