Torex Semiconductor XC980x Regulated Voltage Step-Up Charge Pump ICs provide stable, highly efficient, positive voltages with the only external components required being two capacitors. Ripple current is minimal in these ICs since regulating is done via controlling the charge pump's gate voltage waveform. The output voltage is selectable in 100mV steps within a 2.5V to 6V range. The XC980x charge pump ICs switch to PFM (pulse skip) during light loads without impacting output impedance or ripple. This feature ensures the IC maintains high efficiency even under low load conditions.
