CXDC65102系列是一种同步升压微型DC/DC转换器，它集成了一个电感和
一个微型封装的控制芯片（2.5毫米×2.0毫米，H=1.0毫米）。配置稳定的升压电源
只使用两个外部连接的电容器。内部线圈简化了电路，使电路最小化
由于电路布线而产生的噪音和其他操作故障。CXDC65102系列可用于
由于输入电压范围的原因，从单一碱性或镍氢电池开始的应用
在0.9V~5.5V之间，输出电压可在1.8V~5.0V（±2.0%）范围内按0.1V步进进行。PFM控制
提供低静态电流，使这些产品成为需要高效率的便携式设备的理想选择。
CXDC65102具有负载断开功能，在
关机（CXDC65102A）和旁路模式功能，以保持输入和输出之间的连续性（CXDC65102C）。

一,产品概述(General Description) 
The CXDC65102 series is a synchronous step-up micro DC/DC converter which integrates an inductor and
a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable step-up power supply is configured
using only two capacitors connected externally. An internal coil simplifies the circuit and enables minimization
of noise and other operational trouble due to the circuit wiring. The CXDC65102 series can be used in
applications that start from a single alkaline or nickel-metal hydride battery because the input voltage range
is 0.9V ~ 5.5V. The output voltage can be set from 1.8V to 5.0V (±2.0%) in steps of 0.1V. PFM control
enables a low quiescent current, making these products ideal for portable devices that require high efficiency.
The CXDC65102 features a load disconnect function to break continuity between the input and output at
shutdown (CXDC65102A),and a bypass mode function to maintain continuity between the input and output (CXDC65102C).
