XC9802 - Regulated Voltage Step-Up Charge Pump

Download the XC9802 datasheet PDF. This datasheet also covers the XC9801 variant, as both devices belong to the same regulated voltage step-up charge pump family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • Input Voltage Range : 1.8V ~ 5.5V Output Voltage Range : 2.5V ~ 6.0V Small Input Current : 80μA (no load:XC9802) Output Current : 80mA (3.6V→5.0V step-up) Oscillation Frequency : 300 kHz Stand-by Current (CE ’L’) : 2.0μA (MAX. ) PFM Operation During Light Loads (XC9802) CE (Chip Enable) Function Can be used as a step-up doubler (sense = 0V) Packages : MSOP-8A, USP-8, USP-8B05 Environmentally Friendly : EU RoHS Compliant, Pb Free.

XC9801/XC9802 Series Regulated Voltage Step-Up Charge Pump ICs ETR08004-007b ■ 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.
