Digital power
Implement power supplies across a wide range of topologies while exceeding performance standards and delivering highest efficiency and power density
Flexibility, efficiency and integration for your dynamic system needs
Our easy-to-use digital-power controllers help optimize your power design's performance and cost. Our unique architecture and powerful GUI offer best-in-class loop latency, higher power density, improved accuracy and efficiency. Modern power supplies require advanced control methods and complex topologies like multi-phase or totem-pole power factor correction (PFC), bidirectional or inverting DC/DCs, current mode resonant inductor-inductor-capacitor and synchronous rectification. Our devices require fewer development resources and less time to pass your power-supply specifications.
Select by type
Digital-power controllers
We've optimized our digital-power controllers for existing and new industrial and enterprise markets, including telecommunications and server power, offboard chargers and solar power.
SR MOSFET gate drivers
Synchronous rectifier (SR) MOSFETs are high-speed gate drivers featuring high-drive capability and body-conduction sensing to improve system performance when used with digital-power controllers.
Why choose our digital power controllers?
Comprehensive analog integration
Achieve faster operating frequencies and smaller components with dedicated power peripherals, feedback and high-resolution PWM control to achieve faster control loops and greater power density
Flexible power topologies
Get precise waveform control regardless of topology with high-resolution phase, period and duty-cycle controls. Our controllers are easily programmable for PFC, AC/DC and isolated DC/DC power supplies
Ease of use
Accelerate your development with our Fusion Digital Power™ GUI and fusion express API, and leverage Code Composer Studio™ software for proprietary code development, code debugging and flashing
Power trends
High efficiency digital-power controller
Our digital-power controllers provide dedicated hardware peripherals with simpler firmware development to maximize power density and efficiency with flexbility to implement many power topologies. Developed and optimized for power-supply applications, our digital-power controllers do not limit bandwidth, latency or transient response which saves MIPS for housekeeping or multi-tasking. Dual memeory bank architecture makes firmware updates seamless with zero downtime. Control schemes can be non-linear, zero-voltage switching (reasonant or PWM), with analog modules providing dead-time compensation for higher average efficiency plus robust fault protections.
