LM3668 Datasheet (Texas Instruments) - High-Efficiency Dual-Mode Single-Inductor Buck-Boost DC-DC Converter

LM3668, High-Efficiency Dual-Mode Single-Inductor Buck-Boost DC-DC Converter

The LM3668 is a synchronous buck-boost DC-DC converter optimized for powering low voltage circuits from a Li-Ion battery and input voltage rails between 2.5 V and 5.5 V.

It has the capability to support up to 1-A output current over the output voltage range.

The LM3668 regulates the output voltage o
