Features Fixed 5V ± 4% Output VIN Range: 2.7V to 5V Output Current: Up to 250m A Constant Frequency Operation at All Loads Low Noise Constant Frequency (1.2MHz) Operation Automatic Soft-Start Reduces Inrush Current Shutdown Current <1µA Short-Circuit Protection No Inductors Available in Low Profile 6-Lead SOT23 Package Application White LED Backlighting Li-Ion Battery Backup Supplies Local 3V to 5V Conversion Smart Card Readers PCMCIA Local 5V Supplies Description The XA2320 is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. It produce a regulated output voltage from a 2.7V to 4.5V input with up to 250m A of output current. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the XA2320 ideally suited for small, battery-powered applications. A new charge-pump architecture maintains constant switching frequency to zero load and reduces both output and...
