Ultra-small digital non-isolated IBC has 4:1 conversion ratio
EP&T MagazineElectronics Power Supply / Management converter dc-dc digital Flex-Power IBC non-isolated power
FLEX POWER MODULES BMR314 non-isolated dc-dc converter features a fixed 4:1 down-conversion ratio for intermediate bus applications. The highly power-dense part provides 800 W continuous, 1.5 kW peak from an industry-standard, ultra-small package, sized at 23.4 x 17.8 x 9.6mm. Input range is 38 – 60Vdc (68 Vdc peak) for an output of 9.5 – 15Vdc. Product is targeted at applications such as powering Point of Load (PoL) converters in AI and datacom centers where high peak loads can occur, space is at a premium and energy saving is important. This is enabled by the device with its high efficiency of 97.4% peak in a low-profile package optimized for cold wall cooling. Up to 70A output current is available and the device is fully protected against over-temperature, input under-voltage and output over-current, over-voltage and short circuits. Full control and monitoring are provided through a PMBus interface and the product is supported by the Flex Power Designer software tool for configuration, performance simulation and monitoring.
