REG71055-Q1 描述
The REG71055 is a switched capacitor voltage converter that produces a regulated, low-ripple output voltage from an unregulated input voltage. Input supply voltage of 3.0 V to 5.5 V makes the REG71055 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 below the output voltage and the output remains in regulation. It works equally well for step-up 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 REG71055 is thermally protected and current limited, protecting the load and the regulator during fault conditions.
