TPS62085、TPS62086 和 TPS62087 器件是高频同步降压转换器,经优化具有小解决方案尺寸和高效率两大优点。该器件的输入电压范围为 2.5V 至 6.0V,支持常用电池技术。此器件主要用于宽输出电流范围内的高效降压转换。该转换器在中等程度的负载到高负载时运行于脉宽调制 (PWM) 模式,并在轻负载时自动进入省电模式运行,从而在整个负载电流范围内保持高效率。
为了满足系统电源轨的需求,内部补偿电路支持 10µF 到 150uF 的宽范围外部输出电容值选项。凭借 DCS-Control 架构,该器件可实现出色的负载瞬态性能和输出稳压精度。器件可提供 2mm × 2mm VSON 封装。
