BD8303MUV
2.7-14V 1ch Buck-Boost converter (Controller)

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.

    • Evaluation Board
    • BD8303MUV-EVK-001
    • This Evaluation Board uses a synchronous rectifying buck-boost DC / DC controller IC BD8303MUV to output 12V from an input voltage of 4V to 14V. BD8303MUV accepts a power supply input range of 2.7V to 14V. The output voltage can be set from 1.8V to 12V with an external resistor. The operating frequency can be set from 200kHz to 1MHz with an external resistor. The IC implements an efficient buck-boost converter using one inductor and external N-Channel FETs.
