General Description
ROHM’s highly-efficient step-up/down switching regulator 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.

FEATUREs
1) Highly-efficient step-up/down DC/DC converter to be constructed just with one inductor.
2) Supports a wide range of power supply voltage range (input voltage: 2.7 V - 14.0 V)
3) Supports high-current application with external Nch FET.
4) Incorporates soft-start function.
5) Incorporates timer latch system short protecting function.
6) High heat radiation surface mounted package QFN16 pin, 3 mm × 3 mm

APPLICATION
   General portable equipment like DVC, single-lens reflex cameras, portable DVDs, or mobile PCs
