Do you have any DC to DC (Boost converter ) for battery powered  applications
for unregulated input voltage between 1.8 volts to 4.5 volts, regulated (or
fixed)3.3V output ,Current limits up to 300mA and high efficiency and low
quiescent supply current ?

 

The best part would be the ADP1612 boost regulator. It has a Vin of 1.8V to
5.5V. This can be used as a boost regulator. That means that Vout will be 3.3V,
but with Vin becoming higher than about 3.5V, Vout will go above 3.3V also. If
you are looking for a step-up AND step-down function, so depending on the
actual Vin it will buck or boost, you can use the same device in the SEPIC
topology. Please see the circuit calculator for this under the following link:
