Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9802B583DR-G

The XC9802B583DR-G is a fixed regulated voltage step-up charge pump IC from the XC9802 series, designed to provide stable and efficient positive voltages. It operates within an input voltage range of 1.8V to 5.5V and can output voltages selectable in 100mV steps from 2.5V to 6.0V, with a maximum output current of 80mA when stepping up from 3.6V to 5.0V. The device features a small input current of 80OºA under no load conditions and a low stand-by current of 2.0OºA. The XC9802 incorporates pulse frequency modulation (PFM) during light load conditions to maintain efficiency without compromising output impedance or ripple. It can also function as a voltage doubler when the SENSE pin is connected to ground. The IC is available in compact MSOP-8A and USP-8 packages, making it suitable for battery-operated applications such as power supplies for TFTs, op-amps, and smart cards. The product is compliant with EU RoHS standards and is environmentally friendly.
