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 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 and USP-8B05 packages, the small consumption current and high efficiencies of the series make the XC9801 suitable for use with all types of battery operated applications.●
