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.
