Regulated Voltage Step-Up Charge Pump ICs ç ç ç ç ç ˙çGENERAL 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 SEN SE 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. ˙APPLICATIONS ˔Palm top computers, PDAs ˔On board local power supplies ˔Various battery powered devices ˙TYPICAL APPLICATION CIRCUIT ˙FEATURES Input Voltage Range : 1.8V ~ 5.5V Output Voltage Range : 2.5V ~ 6.0V Small Input Current : 80 ЖA (no load:XC9802) Output Current : 80mA (3.6Vˠ5.0V step-up) Oscillation Frequency : 300kHz Stand-by Current (CE ’L’) : 2.0ЖA (MAX.)

By connecting the SENSE pin to V OUT, 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 P3ʟs 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 ʾ V OUT. 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 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 XC 9802 provides the added security of pr otection against drops in efficiency during light loads as a result of t he pulse, generated by the internal oscilla tor, being skipped and the operating frequency being changed.
