The LTM4605 is a high efficiency switching mode buck boost power supply. Included in the package are the switching controller, power FETs, and support components.

Operating over an input voltage range of 4.5V to 20V, the LTM4605 supports an output voltage range of 0.8V to 16V, set by a resistor. This high efficiency design delivers up to 5A continuous current in boost mode (12A in buck mode). Only the inductor, sense resistor, bulk input and output capacitors are needed to fi nish the design.
