Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9802B353KR-G

The XC9802B353KR-G is a fixed regulated voltage step-up charge pump IC designed for efficient voltage regulation in battery-operated applications. It operates within an input voltage range of 1.8V to 5.5V and provides selectable output voltages from 2.5V to 6.0V in 100mV increments. The device supports an output current of up to 80mA when stepping up from 3.6V to 5.0V, making it suitable for various low-power applications. This IC features a pulse frequency modulation (PFM) operation during light loads, which helps maintain efficiency without compromising output impedance or ripple. The XC9802B353KR-G is packaged in a compact MSOP-8A format, requiring only two external capacitors for operation. It also includes a chip enable (CE) function and can be configured as a voltage doubler by connecting the SENSE pin to ground. The device is compliant with EU RoHS standards, ensuring it is environmentally friendly.
