XC9801/XC9802 Series
Regulated Voltage Step-Up Charge Pump ICs
ETR0802_002
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. 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. 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. Connecting the SENSE pin to the GND pin allows the IC to be used as a voltage Output voltage is

BLOCK DIAGRAM
Controller
(1) Basic Operations
Using the XC9801/02's clock generated by the internal oscillator, a step-up charge pump operation can be brought about as a result of the alternate switching between operating conditions where P1 & N4 are ON with P2 & P3 OFF (or) P1 & N4 are OFF with P2 & P3 ON. By connecting the SENSE pin to VOUT, output voltage can be feedback and the difference between the feedback voltage and the reference voltage (Vref) are compared by the internal operational amplifier. Output voltage can be stabilized (* 2) by controlling P3's gate voltage waveform via the signal generated by the internal amplifier. Please note that this stabilizing function will not operate with VIN < (VOUT/2) or VIN VOUT. By connecting SENSE to ground, the output stability function, as described above, can be halted and the IC can be used as a step-up doubler. * 2 : As a result of P3 gradually reaching an ON state with each clock (signal), rush current is controlled, the ripple decreases and with the combination of the independent phase compensation circuit, output voltage is stabilized (2) Stand-by Function When the voltage at CE (chip enable) is `low' (0V), P1, P2 & P3 will be OFF with N4 & N5 ON. The external capacitor C1 will discharge and impedance at VOUT will be high. (3) PFM (Pulse Skip) Operations Whilst maintaining output voltage, the XC9802 provides the added security of protection against drops in efficiency during light loads as a result of the pulse, generated by the internal oscillator, being skipped and the operating frequency being changed.
