CXTP6509是一种开关电容电压转换器，它从一个不受调节的输入电压中产生一个可调节的、低噪声的、低纹波的输出电压（5V）。即使VIN大于5V，它也保持5V的调节。5V的输出可以提供一个最大的300毫安电流与一个小封装。
在典型情况下，当负载电流低于4mA时，CXTP6509以跳过模式运行。在跳跃模式下，静态电流降低到170uA，只需要3个外部电容器就可以产生输出电压，从而节省了PCB空间。励磁涌流在通电和暂态时受软起动功能的限制。CXTP6509具有内置的电流限制保护，非常适合HDMI、USB OTG和其他电池供电的应用。
CXTP6509有绿色SOT-23-6L包装，环境温度范围为-40℃至+85℃。

一.产品概述
The CXTP6509 is a switched capacitor voltage converter which produces a regulated, low noise, and low-ripple output voltage (5V) from an unregulated input voltage. It maintains 5V regulation even when VIN is greater than 5V. The 5V output can supply a maximum of 300mA current with a small package.
CXTP6509 operates in skip-mode when the load current falls below 4mA under typical condition. In skip-mode operation, quiescent current is reduced to 170uA.Only 3 external capacitors are needed to generate output voltage, thereby saving PCB space. Inrush current is limited by the soft start function during power on and power transient states. The CXTP6509 has built-in current limit protection that is ideal for HDMI, USB OTG and other battery powered applications.
The CXTP6509 is available in Green SOT-23-6L package and is specified over an ambient temperature range of -40℃ to +85℃.
