ROHM BD8306MUV-E2, 1 Buck Boost Switching, Boost/Buck Converter 1A, 1.1 MHz 16-Pin, VQFN

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.

Highly-efficient step-up/down DC/DC converter to be constructed just with one inductor.
Input voltage 1.8V-5.5V
Output current 1 A at 3.3V 700mA at 5.0V(Input voltage 2.8V-5.5V)
Incorporates soft-start function.
Incorporates timer latch system short protecting function.
