TOREX SEMICONDUCTOR
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 pumps gate voltage waveform, ripple is minimal. Output voltage is selectable in 0.1V steps within a 2.5V ~ 5.2V range.
FEATUREs
Input Voltage Range : 1.8V ~ 5.5V
Output Voltage Range : 2.5V ~ 5.2V
Small Input Current : 80µA (no load:XC9802)
Output Current : 80mA (3.6V→ 5V step-up)
Oscillator Frequency : 300kHz
Stand-By Current (CE L) : 2.0µA (max)
Can be used as a Step-Up Doubler (sense = 0V)
