General Description
The LM3668 is a synchornous buck-boost DC-DC converter optimized for powering low voltage circuits from a
Li-Ion battery and input voltage rails between 2.5V and 5.5V. It has the capability to support up to 1A output
current over a output voltage range of 2.8V/3.3V. The LM3668 regulates the output voltage over the
complete input voltage range by automatically switching between buck or boost modes depending on the
input voltage.
The LM3668 has 2 N-channel MOSFETS and 2 P-channel MOSFETS arranged in a topology that provides
continuous operation through the buck and boost operating modes. There is a MODE pin that allows the user
