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.
