数据: TPS6262x 600-mA, 6-MHz High-Efficiency Step-Down Converter In Chip Scale Packaging 数据表
TPS6262x器件系列提供针对电池供电的便携式应用而优化的高频同步降压DC /DC转换器。 TPS6262x器件专为低功耗应用而设计,可支持高达600 mA的负载电流,并允许使用低成本芯片电感和电容。
具有2.3 V至5.5 V的宽输入电压范围,这些器件支持由具有扩展电压范围的锂离子电池供电的应用。不同的固定电压输出版本可在1.2 V至2.3 V范围内使用。
TPS6262x器件以6 MHz的稳定开关频率工作,并在轻负载电流下进入省电模式,以保持高效率整个负载电流范围。
脉冲频率调制(PFM)模式通过在轻负载和待机操作期间将静态电流降至31μA(典型值)来延长电池寿命。对于噪声敏感应用,可以通过将MODE引脚拉高来强制器件进入固定频率脉冲宽度调制(PWM)模式。
TPS6262x器件可在-40°C的自由空气温度范围内工作到85°C。它们采用6引脚芯片级封装(WCSP)。
