This project shows a DC-DC buck boost circuit which can produce an output of 3.3V for an input of 2.7V to 4.2V , for example from a Li-on battery. The Circuit uses LTC3440 Buck boost IC which is a fixed frequency boost converter. To get high efficient results, inductor with high frequency core material should be used.

Features

  • Input(V): 2.7V DC to 4.2V DC
  • Output(V): 3.3V DC
  • Output load: 600mA
  • PCB:23mmX15mm
