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.

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