XC9801 Series
Step-Up Charge Pump
General Description
Features
The XC 9801 series are step-up charge pump IC s which
provide stable, highly efficient, positive voltages with the only
external components required being 2 capacitors. Output
voltage is selectable in 0.1V steps within a 2.5V ~ 5.2V range
and with output stabilised through the control of the charge
pump's output impedance, ripple is minimal.
Control switches to PFM (pulse skip) during light loads
without affecting output impedance or ripple so that the IC is
protected against drops in efficiency.
As well as the ultra small MSOP-8 package, the small con-
sumption current and high efficiencies of the series make the
XC 9801 suitable for use with all types of battery operated ap-
plications.
