Introduction

AI Translation

TPS54020 是一款 10A、4.5V 至 17V 输入 SWIFT 转换器。该器件采用创新型 3.5mm × 3.5mm HotRod 封装，可优化高密度降压设计。TPS54020 是一款功能全面的转换器。 通过高侧和低侧 MOSFET 的创新集成与封装实现了高效率。TPS54020 可在较高负载条件下保持连续电流模式 (CCM) 运行，并能在跳过脉冲时切换至 Eco 模式以提升轻载效率。 两个 MOSFET 上的电流限制提供器件和系统保护。高侧 MOSFET 内的逐周期电流限制在过载情况下提供保护。低侧 MOSFET 零电流检测在轻载运行时关闭低侧 MOSFET。共有三种限流阈值可供选择，适用于多种应用场景。也可选择断续或逐周期过流保护机制。 当芯片温度超过热关断触发点时，热关断保护禁用开关，并在内置热滞后和关断断续时间后重新启用开关。 SS 引脚控制输出电压启动斜坡，并支持可选择的软启动时间。通过配置使能 (EN) 引脚和开漏电源正常 (PWRGD) 引脚，还可实现电源时序控制。 两个 TPS54020 器件可通过 SYNC_OUT 和 CLK 引脚实现 180° 异相同步。
