Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9801B403KR-G

The XC9801B403KR-G is a fixed regulated voltage step-up charge pump IC from the XC9801 series, designed to provide stable and efficient positive voltages. It operates within an input voltage range of 1.8V to 5.5V and offers selectable output voltages from 2.5V to 6.0V in 100mV increments. The device can deliver an output current of up to 80mA when stepping up from 3.6V to 5.0V, with a minimal ripple due to its control of the charge pump's gate voltage waveform. This IC features a small input current of 80OºA under no load conditions and a low stand-by current of 2.0OºA maximum. It operates at an oscillation frequency of 300 kHz and includes a chip enable (CE) function for power management. The XC9801B403KR-G is packaged in an ultra-small MSOP-8A format, making it suitable for space-constrained applications, particularly in battery-operated devices. Additionally, it is compliant with EU RoHS standards, ensuring it is environmentally friendly.
