Pulsiv launches cost optimised 75W, 100W reference designs

UK startup Pulsiv has developed two reference designs for 7W and 100W power supplies using its Osmium architecture that eliminates in-rush currents.

The Osmium microcontrollers and AC to DC front-end circuit configurations are already available and the company has used these for the first in a series of reference designs.

Eliminating the in-rush current means that components can be smaller and can operate at low temperatures to extend expected lifetime and ensure long-term reliability even under convection cooling as well as removing the need for additional current limiting components.

The cost-optimised reference designs offer 75W (85W peak) & 100W (150W peak) output power with universal mains input and 48V output.

Front end AC-DC architecture slashes size

The Osmium microcontroller and supporting components have been combined with a quasi-resonant flyback DC-DC converter to deliver an end-to-end flat efficiency of 90% (91.5% peak) from just 10W, comfortably exceeding the US DoE Level VI and EU CoC Tier 2 requirements.

The reference designs can be further optimised using GaN and SiC technology where performance or size are more important than cost.

Design packages can be downloaded from which provide a comprehensive Datasheet, Bill of Materials, Schematic and full set of Altium files.

Manufacturers of industrial power supplies and LED lighting solutions can benefit further by simplifying designs and improving system installations.

“Tackling the global energy crisis and delivering ambitious sustainability targets will require the electronics industry to embrace technology innovation and challenge conventional thinking. Pulsiv OSMIUM reference designs offer a cost effective method to reduce the amount of energy consumed in AC to DC power supplies and battery chargers under all operating conditions,” said Darrel Kingham, CEO of Pulsiv.
