Overview

TPS568215OA是一款高密度同步降压转换器，输入电压（VIN）范围为4.5 V至17 V，集成19 mΩ和9 mΩ MOSFET，最高效率可达10 A。该器件采用D-CAP3™控制模式，无需外部补偿元件即可实现快速瞬态响应，并具备精确的反馈电压。控制拓扑可在重载时的FCCM工作模式与轻载时的OOA工作模式之间无缝切换。OOA功能使TPS568215OA的开关频率保持在可听频率范围以上。TPS568215OA兼容低ESR输出电容（如POSCAP或SP-CAP）及超低ESR陶瓷电容。 TPS568215OA提供三种可选开关频率（FSW）：400 kHz、800 kHz和1200 kHz，可灵活优化设计以兼顾高效率或小尺寸需求。电流限制同样提供三档可选。所有这些选项均通过在MODE引脚上设置相应电压进行配置。 TPS568215OA内置4.7 V LDO，为所有内部电路提供偏置电源。用户可通过VREG5引脚施加外部电压来旁路该内部LDO，从而提升转换器效率。欠压锁定（UVLO）电路监测VREG5引脚电压，防止内部电路在低输入电压下损坏。EN引脚内置上拉电流源，引脚悬空时器件亦可正常使能。软启动时间可通过在SS引脚连接电容进行配置。器件具备输出短路、欠压及过温保护功能。
