XC9801/XC9802 Series Regulated Voltage Step-Up Charge Pump ICs provide stable, highly efficient, positive voltages with the only external components required being 2 capacitors.
The XC9801/XC9802 series are fixed regulated voltage step‑up charge‑pump ICs that provide stable, highly efficient positive voltages using only two external capacitors. Output voltage can be set in 100 mV steps within a 2.5 V – 6.0 V range, and the XC9802 switches to pulse‑skip (PFM) mode under light loads to maintain efficiency. The devices are supplied in ultra‑small MSOP‑8A and USP‑8 packages and are suited for battery‑operated applications.
Key electrical characteristics include an input voltage range of 1.8 V – 5.5 V, standby current of 2.0 µA (max), oscillation frequency of 300 kHz, and a maximum output current of 200 mA. Typical application circuits and performance graphs illustrate voltage regulation, efficiency, and ripple behavior across load conditions.

The devices operate with an input voltage from 1.8 V up to 5.5 V.
The XC9802 switches to pulse‑skip (PFM) mode during light loads, reducing power consumption while maintaining output voltage.
Yes, connecting the SENSE pin to ground enables the IC to operate as a step‑up voltage doubler.
