产品概要
背景
年来,在以5G通信基站和FA设备为首的先进工业设备中,越来越多地配备了融和AI和IoT技术的新功能。随之而来的是对所使用的电源IC提出了越来越高的要求:不仅要小型高效,还要具有高耐压性能,以确保即使受到雷电等引起的突发性浪涌电压也不会损坏;而且还要能支持大电流,以使众多功能工作。
ROHM利用先进的电源系统工艺和垂直统合型生产体制,为工业设备市场开发出众多电源IC产品,这些产品不仅特性出色,而且还很注重可靠性和长期稳定供应。此次,ROHM又面向先进的工业设备领域,开发出高耐压和大电流性能兼备的DC/DC转换器IC。

概要
“BD9F500QUZ”适用于24V电源系统,采用小型薄型封装(3.0mm×3.0mm×0.4mm),虽然小巧却实现了39V的耐压和5A的输出电流,有助于以FA设备为首的众多先进工业设备实现更高性能和更小体积。

特点
1. 通过节省安装面积和削减部件数量,有助于应用产品降低成本并更加小型化
BD9F500QUZ是内置MOSFET(同步整流型*4)的非隔离型DC/DC转换器IC,利用ROHM的模拟设计技术优势,以小型封装(3.0mm×3.0mm×0.4mm)实现了39V的耐压和5A的输出电流。与具有同等性能的普通产品(6.0mm×4.0mm×0.8mm)相比,尺寸减少约60%,而且还可以减少外围部件的数量。不仅如此,利用高达2.2MHz的高速开关性能,即使使用1.5µH的小型线圈也能实现稳定工作,可节省在电路板上的安装面积并可降低高度,从而有助于PLC和逆变器等各种FA设备的主电源系统的24V线应用降低部件成本并实现小型化。

2. 高效率和低发热量运行,有助于提高可靠性
BD9F500QUZ虽然采用的是不利于散热的小型封装,而且还支持高速开关,但仍然能够以很低的发热量工作。在具有同等功能的小尺寸产品中,IC温度接近100℃,因此需要采取散热措施(通过外置散热器和MOSFET来分散热量),而ROHM新产品的工作效率高达90%(输出电流为3A时),并采用散热性能出色的封装,工作时的发热温度仅为65℃左右,因此客户无需采取散热措施,从而有助于提高应用的可靠性。

- Power Management Reference design for Xilinx FPGA Spartan-7 platform
ROHM, together with Avnet, a leading supplier of electronic products and embedded solutions, developed a reference power supply optimized for Xilinx’s FPGA Spartan-7. In recent years, FPGA power supplies are increasingly demanding high accuracy low voltage, complicated startup sequences. At the same time, designers are constantly faced with the need to upgrade their designs to feature smaller form factors, greater energy savings, and lower costs, which are difficult to achieve within a short period. In response, ROHM offers an optimized power supply reference design for FPGA power supplies that allows designers to reduce development load while meeting market demands. The Spartan-7 (which this reference design was developed for) is ideal for industrial and consumer applications that leverage connectivity with sensor fusion and embedded vision. ROHM’s reference power supply design consists of a verified power supply that safely starts and operates Xilinx’s Spartan-7. This reference power supply includes the BD95602MUV power supply IC that delivers superior response characteristics, along with the BD9B305QUZ, BD9F500QUZ, and BD9F800MUZ designed to provide the current capability demanded for each power supply as well as the BD35395EFJ-M DDR3L termination power supply, making it possible to generate supply voltages that meet FPGA voltage accuracy specifications from 12V input while also supporting the necessary startup sequence. Reference design materials including circuit diagrams, BOMs, and board layouts are available for download.
