XC9276 Series ETR05070-001 Ultra-Low Quiescent Current, Synchronous Step-Down PFM DC/DC Converter
with Output voltage selectable function
☆Green Operation compatible ■GENERAL DESCRIPTION
The XC9276 Series is a 150mA step-down synchronous rectification DC/DC converter which has an output voltage switchover function with an ultra-low power consumption circuit and a PFM control.
The efficiency performance at a light load current is dramatically improved by implementing ultra-low power consumption
circuits which has 200nA consumption current, and PFM control method. Additionally two-preset output voltage switchover
function is available with using VSEL pin.
This function can select an appropriate output voltage based on the MCU behavior mode and contribute a power
consumption reduction for a total system. Due to these functions, XC9276 series are suitable for equipment which needs a
high efficiency performance at a light load current, and a long-time battery life.
XC9276 series are compatible to 2.2uH inductor therefore it can reduce an output ripple voltage which is a negative side of
PFM control method, and a PCB board area size. ■FEATURES ■APPLICATIONS

详细说明

XC9276系列是超低静态电流同步整流型PFM降压DC / DC转换器，具有内置0.3Ω（TYP。）Pch驱动器和0.3Ω（TYP。）Nch同步开关晶体管，具有输出电压可选功能，旨在允许使用陶瓷电容器。

PFM控制可实现超低静态电流，因此这些产品非常适合需要高效率和长电池寿命的电池供电设备，仅需要电感器，CIN和CL电容器作为外部零件即可构成降压DC / DC电路。电压范围为1.8V至6.0V。本产品具有固定的两个输出电压，范围为0.6V至3.6V（精度：±2.0％），增量为0.1V。通过SET端子，可以在两个预设电压中选择输出电压，以根据应用状况提供理想电压。待机期间，所有电路都将关断，以将功耗降至0.1μA或更小。
