Showcasing new bus converter together with power conversion products

Flex Power Modules will be showcasing new products at the electronica 2022. One product, to be launched at the event, will be an 8:1 ratio, 400W intermediate bus converter with excellent efficiency and power density figures. The product is non-isolated and unregulated and supplies 5VDC to 7.5VDC output from a 40-60VDC input. This matches the movement for 48V or 54VDC nominal input voltages and a lower voltage intermediate bus, to allow high efficiency voltage regulator modules to be employed. The device has a PMBus interface for monitoring and control and is remarkably compact in size (27mm x 18mm x 6.4mm or 1.06" x 0.71" x 0.25").

The company's BMR313 product will also be displayed. Developed in conjunction with onsemi and pre-released in October 2022, this intermediate bus converter is rated at 1kW continuous and 3kW peak with a power density of 941W/cm3. The converter provides a conversion ratio of 4:1 and delivers 97.3% efficiency at 54VDC input. The product is thermally optimised for cold wall cooling and is offered in an industry standard LGA footprint and pinout.

These parts and the complete DC-DC power conversion products range suitable for telecom, datacom and industrial applications can be seen on their booth.

The company will also be speaking at the Embedded Platforms Conference 2022, hosted at electronica, with a presentation entitled ‘Peak Load Power Management by DC-DC Converters’ by Mikael Appelberg, CTO.
