BD8305MUV - High-effciency Step-up/down Switching Regulators

General Description

ROHM’s highly-efficient step-up/down switching regulator BD8305MUV produces step-up/down output including 3.3 V from 1 cell of lithium battery with just one coil.This IC adopts an original step-up/down drive system and creates a higher efficient power supply than conventional Sepic-system or H-bridg

Key Features
