GENERAL DESCRIPTION
The The T6319A is a switched capacitor voltage converter, that produces a regulated, low ripple output voltage from an unregulated input voltage. A wide-input supply voltage of 2.5V to 5.5V makes the T6319A ideal for a variety of battery sources, such as single cell Li-Ion, or two and three cell nickel or alkalinebased chemistries. The input voltage may vary above and below the output voltage and the output will remain in regulation. It works equally well for step-up or step-down applications without the need for an inductor, providing low EMI DC/DC conversion. The high switching frequency allows the use of small surface-mount capacitors, saving board space and reducing cost. The T6319A is thermally protected.
