MAS9251 is a low noise, constant frequency
switched capacitor voltage doubler with regulated
output. In the adjustable output version an external
feedback pin allows the output voltage to be
adjusted.
The high switching frequency of MAS9251
guarantees low output ripple even with small
ceramic capacitors. The shutdown control pin can
be used to turn off the device for power saving.
MAS9251 is equipped with soft-start feature, which

reduces the circuit’s disturbance to power supply
lines during start-up by limiting the maximum input
current.
Low operating input voltage and low external part
count make MAS9251 ideal for small battery
powered portable systems. An internal thermal
