数据： 采用 1.5mm × 1.5mm QFN 封装且具有 1% 输出精度的 TPS6282x 2A 或 3A 降压转换器 数据表
TPS6282x是一款易于使用的通用型同步降压直流/直流转换器，具有仅4μA的极低静态电流。此系列器件具有2.4 V至5.5V的输入电压，可提供高达3A的输出电流（TPS62826）。该系列器件可基于DCS-Control™拓扑提供快速瞬态响应。
由于具有内部基准，该系列产品可在-40°C至125°C的结温范围内以高达1％的反馈电压精度将输出电压调节到低至0.6V。整个引脚对引脚器件系列可与470nH的小型电感器结合使用并且可实现BOM对BOM兼容。
TPS6282x可在超轻负载时自动进入省电模式，并保持高效率。该器件具有电源正常信号和内部软启动电路。它能够以100％模式运行。在故障保护方面，它加入了断续电流限制以及热关断功能。该系列器件可提供6引脚1.5 x 1.5mm QFN封装。
