TPS53915 具有实现高功率密度的 PMBus 控制的 1.5V 至 18V DCAP3 12A 同步降压转换器

描述

TPS53915是一款具有自适应接通时间D-CAP3控制模式的小尺寸，同步降压转换器。此器件使空间受限电源系统易于使用，并且外部组件数量较少。

该器件特有高性能集成MOSFET，精度为0.5％的0.6V电压基准和一个集成的升压开关。具有竞争力的特性包括：极低外部组件数量，快速负载瞬态响应，自动跳跃模式操作，内部软启动控制，并且无需补偿。此外，该器件还具备可编程性和故障报告特性，这些特性通过PMBus实现，以简化电源设计。

强制持续传导模式有助于满足数字信号处理器（DSP）和现场可编程门阵列（FPGA）性能实现所要求的严格电压调节精度.TPS53915采用28引脚QFN封装，并且在-40°C至85°C的环境温度范围内额定运行。
