The LTC3113 is a single inductor buck-boost converter that offers a compact, highly efficient alternative. Internal low resistance switches allow the converter to support an impressive 3A of load current in a tiny 4mm × 5mm package. The LTC3113 offers an extended input and output operating voltage range from 1.8V to 5.5V, with peak efficiencies reaching 96%.
The document introduces the LTC3113 as a single inductor buck-boost converter that addresses challenges with input voltages above or below the regulated output. It highlights features such as 96% peak efficiency, an operating frequency range of 300kHz to 2MHz, and internal low resistance switches for high power density.
