【产品】开关频率1MHz的高频升压转换器芯片TPS61040/1,可调输出电压范围高达28V
TPS61040和TPS61041是华冠半导体推出的高频升压转换器芯片,专用于中小型LCD偏置电源和白光LED背光电源。它们非常适合从双节NiMH/NiCd电池或单节锂离子电池产生高达28V的输出电压。该系列产品还可用于产生标准的3.3V/5V至12V的电源转换。
TPS61040和TPS61041能够以高达1MHz的开关频率工作。它们允许使用小型外部组件,比如使用陶瓷和钽输出电容器。该系列产品采用薄的SON封装,可以提供非常小的整体解决方案尺寸。
TPS61040具有内部400mA的开关电流限制,而TPS61041具有250mA的开关电流限制,可提供更低的输出电压纹波,并允许在低功耗应用中使用更小的电感器。它们的低静态电流(典型值为28μA)与优化的控制方案组合在一起,允许器件在整个负载电流范围内以非常高的效率工作。
c和TPS61041的输入电压范围为1.8V至6V。它们采用SOT23-5封装,封装和引脚配置如图1所示,典型应用电路如图2所示,主要应用于LCD偏置电源、用于LCD背光的白光LED电源、数码相机、PDA和手持电脑、手机、网络音频播放器以及标准3.3V/5V至12V转换等领域。

【选型】可替换TI TPS61040的国产升压DCDC SGM6601助力LCD背光驱动设计,输出电压值可高达38V
在LCD背光驱动电路设计时,一般会用到TI的升压芯片TPS61040做偏置电压电路。但随着国产化和成本压力日益增大,很多厂商急需一颗国产高性价比替换物料。本文重点推荐圣邦微的升压DCDC SGM6601可完美替换TPS61040。相比TI的TPS61040,SGM6601的输出电压值可高达38V;在静态功耗方面,SGM6601的表现更出色。
