This circuit can produce an output of 3.3V and 1A current continuously for a voltage input varying from 2.5V to 4.2V. The LTC3441 is a high efficient buck boost converter which plays a vital role in portable instrumentation because of its fixed frequency operation. This circuit produces the output from a single Li-ion battery. Multiple cells can also be used within the specified range of input voltage.

Features

Input(V): 2.5V DC to 4.2V DC
Output(V): 3.3V DC
Output load: 1A
PCB:21mmX12mm
