REG711-50mA Exchange Section DC/DC Converter
The REG711 is a switched capacitor voltage converter which produces a regulated, low ripple output voltage from an unregulated input voltage. The wide 1.8V to 5.5V input supply voltage makes the REG711 ideal for a variety of battery sources, such as single-cell Li-Ion, or two or three cell nickel or alkaline based chemistries. The input voltage may vary above and below the output voltage and the output voltage will remain within regulation. It also works in one step up or down 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 REG711 is thermal protection and current limit protects the load and regulates under fault conditions. Typical ground pin current (quiescent current) is 1mA at full load, 60µA with no load, and less than 1µA in shutdown mode. The regulator has a thin MSOP-8 package with a component height of no more than 1.1mm.
