The STBLW35 is an ultra-low power and high-efficiency buck-boost DC-DC converter which can work as boost or buck-boost according to the selected hardware configuration. When in buck-boost the DC-DC can seamlessly switch between the two working modes depending on operating conditions. A buck converter step-down converter is a DC-to-DC power converter which steps down voltage while drawing less average current from its input supply to its output load.
It is a class of switched-mode power supply SMPS typically containing at least two semiconductors a diode and a transistor although modern buck converters frequently replace the diode with a second transistor used. Buck-boost converters are ideal for use in portable devices where the power source is frequently a single battery. The battery voltage can swing from a value above that needed by the circuit at full charge to a value below what is needed as the battery discharges.
The buck-boost converter will step-down the voltage in the former situation. Buck converter is having a wide range of use in low voltage low power applications. Multiphase version of buck converters can provide high current with low voltage.
Therefore it can be used for low voltage high power applications. Buck-boost converters are equivalent to flyback converters that use a single inductor instead of a transformer. They have two different topologies inverting and non-inverting and are used as switching regulators which use a switching element typically one or two MOSFETs and an energy storage device such as an inductor to regulate input voltage to lower or higher output voltage.
