通孔安装 BMR684 is targeted at RFPA applications needing a 50 V supply at up to 14 A for gallium nitride (GaN) or laterally diffused MOSFET (LDMOS) power amplifiers, and a wide adjustment range of 25–55 V is offered to help system designers achieve the optimum efficiency and linearity of the power amplifier.
The device achieves an impressive 96% efficiency at full load, and has a maximum baseplate operating temperature of 100°C. The converter input range is 36–75 VDC and a remote control function is included, along with remote sense. Input-output isolation is 1,500 VDC, and the device is packaged in the industry-standard quarter brick format measuring 58.4 x 36.8 x 12.7 mm (2.3 x 1.45 x 0.5 in).
该产品具备全面的保护功能，可防止输入欠压、过温、输出过压、过流和短路。与我们所有的DC/DC转换器一样，这些产品符合IEC/EN/UL 62368-1安全标准。.
目前 BMR684 包含 PMBus™ 该设备提供便捷的接口，方便用户监控输入输出电压、输出电流和设备温度。用户还可以配置设备的诸多运行参数，包括电压和电流，以提高容错能力，并优化模块的控制回路，确保在各种环境下稳定运行。电源管理功能还包括可配置的软启动/停止、精确延时和斜坡上升，并且该产品完全支持强大的电源管理功能。 Flex Power Designer 工具.
Flex 功率模块产品管理和营销总监 Olle Hellgren 表示：“射频功率放大器领域的客户一直在寻找基于 GaN 和 LDMOS 的无线电单元设计中功率密度更高的解决方案，而新型 BMR684 能够提供以往只有半砖封装才能实现的功率水平，再加上 PMBus 接口的优势，我们相信这是一个成功的组合。”
We will be contributing to the embedded world Power Supply Conference, with a presentation entitled ‘Peak Load Management by Communication with DC/DC Converters.’ The presenter is Giorgio Mauri, Senior Principal Field Applications Engineer at Flex Power Modules.
新的 BMR684 as well as the whole product portfolio will be on display at the Flex Power Modules booth.
