TPS546C20A器件是采用 5mm × 7mm 封装且符合 PMBus 1.3 规范的非隔离式 DC-DC 转换器,集成了 FET,能够在高频下运行并输出 35A 电流。两个 TPS546C20A器件可以并联,以便产生高达 70A 的负载电流。通过针对少量功率级电流进行采样实现电流感测,与器件温度无关。集成 NexFET 功率级和优化驱动器提供高频低损耗开关功能,可实现超高密度电源解决方案。PMBus 接口通过 VOUT_COMMAND 启用 AVS 功能,同时支持灵活转换器配置以及关键参数监控功能(包括输出电压、电流和内部芯片温度监控)。对故障条件的响应可设为重启、锁存或忽略,具体取决于系统要求。
