TPS62097-Q1 器件是一款同步降压转换器,经优化可用于高效率和噪声关键 应用。此器件主要用于宽输出电流范围内的高效转换。在中等负载至重负载状态下,此转换器在 PWM 模式下运行,且会在轻负载下自动进入节能运行模式。可使用外部电阻器在 1.5MHz 至 2.5MHz 范围内选择开关频率。iDCS-Control 可在强制 PWM 模式下以恒定开关频率实现低噪声运行。
为了解决系统电源轨的需求,内部补偿电路支持使用电容值高于 150µF 的各种外部输出电容器。为在启动过程中控制浪涌电流,此器件通过连接至 SS/TR 引脚的外部电容器提供了可编程软启动功能。SS/TR 引脚还可用于电压跟踪配置中。此器件还集成了短路保护、电源正常和热关断 功能。
