1.8-5.5V 1A 1ch Buck-Boost converter - BD8306MUV

ROHM’s highly-efficient buck-boost converter BD8306MUV produces step-up/down output voltage including 3.3 V from two-cell or three-cell alkaline battery, or one-cell lithium-ion battery with just one inductor. This IC adopts an original step-up/down drive system and creates a higher efficient power supply than conventional Sepic-system or H-bridge system switching regulators.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
