Power Supply Solutions
This is the future of power supply design
Using a patented switching technique, Pulsiv has developed an entirely new method for converting AC to DC that delivers a combination of game changing benefits in power electronics designs. Our unique technology has extended the range of conventional flyback topologies to replace expensive LLC solutions, whilst achieving an unrivalled efficiency profile.
We offer an intelligent microcontroller, development system for front-end evaluation and a full range of downloadable documents to simplify the design process. Pulsiv OSMIUM provides a scalable platform for engineers to reduce size, improve energy consumption and optimise cost when designing a power supply for virtually any mains powered or battery charging application.

Delivering a unique combination of benefits
Unrivalled Efficiency Profile From Low Power to Full Load
A Pulsiv OSMIUM front-end solution exceeds the Energy Star VI standard by up to 20%. This enables the use of flyback technology at higher power levels, simplifies the design process, and can improve overall energy consumption.
Replace LLC Designs with Flyback Technology
Conventional LLC designs can now be replaced with more cost effective flyback solutions when paired with Pulsiv OSMIUM technology. Our unique approach can extend the range of efficient flyback designs (180W single-switch and 350W interleaved with universal input) to reduce losses and improve overall energy consumption.
Improved Thermal Performance for Higher Reliability
In a Pulsiv OSMIUM design, critical components operate at temperatures far lower than conventional power supplies. This reduces component failures and extends expected life time, even under convection cooling.
Inrush Current Eliminated
By regulating the flow of mains to the charging capacitor, Pulsiv has become the first company in the world to completely eliminate inrush current. For manufacturers of Industrial Power Supplies/LED drivers, system design, installation and cost is significantly improved.
Integrated Features
For complete design flexibility, Pulsiv OSMIUM offers a variety of integrated features which can be used according to the needs of the application and the desired output power.
Scalable Platform
The Pulsiv OSMIUM microcontroller does not directly determine the output power. Changing only 3 key components (Inductor, Mosfet & Capacitor), ensures it can be used across a family of products.
Seamless System Integration
Circuit configurations combine a Pulsiv OSMIUM microcontroller and various supporting components to deliver a complete AC-DC front-end design. Full reference designs combine a front-end circuit configuration with a pre-selected DC-DC converter to deliver an end-to-end solution that meets the relevant EMC/FCC regulations.
Products
Microcontrollers
Pulsiv OSMIUM microcontrollers facilitate the entire AC to DC conversion process and different variants are available to support a range of features/functions. They can be used in any circuit configuration or reference design to unlock all of the benefits that Pulsiv technology has to offer. Quality, reliability, performance and availability have been addressed by combining our unique IP with industry standard devices from carefully selected global tier 1 chip manufacturers.
