2.7-14V 1ch Buck-Boost converter (Controller) - BD8303MUV
BD8303MUV generates step-up/down output including 3.3 V / 5 V from 1 cell of lithium battery, 4 batteries, or 2 cells of Li batteries 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.
