Description

The REG710 is a switched capacitor voltage converterthat produces a regulated, low-ripple output voltage from an unregulated input voltage. A wide input supply voltage of 1.8V to 5.5V makes the REG710 ideal for a variety of battery sources, such as single-cell Li-Ion, or two- and three-cell nickel- or alkaline-based chemistries.

The input voltage may vary above and below the output voltage and the output remains 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 REG710 is thermally protected and current limited, protecting the load and the regulator during fault conditions.
