The ET2110 Charge Pump is a MicroPower switched-capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the ET2110 can deliver up to 100mA to the voltage regulated output. The ET2110 features very low quiescent current and high efficiency over a large portion of its load range making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space restricted applications. The ET2110 operates in an output-regulated voltage doubling mode. The regulator uses a pulse-skipping technique to provide a regulated output from a varying input supply. The ET2110 contains a thermal management circuit to protect the device under continuous output short circuit conditions.
The ET2110 is available in a Pb-free, surface mount SOT23-6 package and DFN6 package and is rated over the -40°C to 85°C.
