XC9801/02 Series
The XC9801 series are fixed regulated voltage step-up charge pump ICs which
provide stable, highly efficient, positive voltages with the only external
components required being 2 capacitors.
Since regulating is done via the control of the charge pump's gate voltage
waveform, ripple is minimal. Output voltage is selectable in 0.1V steps within a
2.5V ~ 5.2V range.
Control of XC9802 switches to PFM (pulse skip) during light loads without
affecting output impedance or ripple so that the IC is protected against drops in
efficiency. Connecting the SENSE pin to the GND pin allows the IC to be used
as a voltage doubler.
As well as the ultra small MSOP-8A and USP-8 packages, the small
consumption current and high efficiencies of the series make the XC9801
suitable for use with all types of battery operated applications.
