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.
