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.

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.
