XC9801/XC9802 Series
Regulated Voltage Step-Up Charge Pump ICs
ETR0802_004
■ GENERAL DESCRIPTION
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 100mV steps within a 2.5V ~ 6.0V range.
Control of the 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.
