The CP2128 are low noise, constant frequency switched capacitor voltage
doublers. They produce regulated output voltage from a 2.7V to 4.5V input with
up to 100mA of output current. Low external parts count make the CP2128 ideally
suited for small, battery-powered application. A new charge-pump architecture
maintains constant switching frequency to zero load and reduces both output and
input ripple. The CP2128 have thermal shutdown capability and can survive a
continuous short circuit from Vout to GND. High switching frequency enables the
use of small ceramic capacitors.
