数据: TPS6104x Low-Power DC-DC Boost Converter in SOT-23 and WSON Packages 数据表
TPS6104x是一款高频升压转换器,专用于中小型LCD偏置电源和白光LED背光电源。该器件非常适合从双节NiMH /NiCd或单节锂离子电池产生高达28 V的输出电压。该器件还可用于产生标准的3.3V或5V至12V功率转换。
TPS6104x的开关频率最高可达1 MHz。该频率允许使用陶瓷和钽输出电容器的小型外部元件。与薄WSON封装一起,TPS6104x提供了非常小的整体解决方案尺寸。 TPS61040器件具有内部400mA开关电流限制,而TPS61041器件具有250mA开关电流限制,可提供较低的输出电压纹波,并允许在较低功率应用中使用较小的外形尺寸电感器。低静态电流(通常为28μA)和优化的控制方案允许器件在整个负载电流范围内以非常高的效率工作。
