Relaciones de conversión de IBC: cómo elegir entre 4:1 y 8:1
BMR321
750 W non-isolated unregulated Intermediate Bus Converter
Características principales
El BMR321 is a non-isolated, unregulated Intermediate Bus Converter (IBC) housed in a package measuring just 41.47 x 17.67 x 6.9 mm (1.63 x 0.7 x 0.26 in) designed for the OCP OAM v2.0 standard, and delivers 750 W of continuous output power and a peak power of 1,500 W over an input voltage range of 40–60 V.
El dispositivo no regulado utiliza una relación fija de 8:1, lo que significa que el voltaje de salida varía de 5 a 7,5 V, ideal para aquellas aplicaciones que requieren un voltaje de bus intermedio más bajo que puede ser útil para optimizar la eficiencia general del sistema cuando se utiliza junto con un controlador posterior. POLs, VRMs, or Integrated Power Stages such as the BMR510 y otros.
With efficiency peaking at 98.05%, up to two units can be paralleled with the inclusion of a SYNC pin to provide a total load of 1,500 W continuous. The parts are mechanically and thermally designed for top-side cooling to a heatsink with airflow, or for liquid cooling via a thermal block, with the open deck baseplate on the topside of the converter allowing for easy connection via a thermal interface material such as a gap pad.
The BMR321 protection features include output current limit and over-voltage, along with over-temperature and input under-voltage. A PMBus® interface is included for monitoring, configuration, and control, and the part is supported by the Herramienta de diseño de potencia Flex.
Al igual que todos los convertidores CC/CC de los módulos de potencia Flex, cumple con las normas de seguridad IEC/EN/UL 62368-1.
