BD8301MUV

www.DataSheet4U.com Single-chip Type with Built-in FET Switching Regulator Series High-efficiency Step-up/down Switching Regulator with Built-in Power MOSFET BD8301MUV No.09027ECT07 ●General Description ROHM’s highly-efficient step-up/down switching regulator BD8301MUV 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-bridge system switching regulators. ●Features 1) Highly-efficient step-up/down DC/DC converter to be constructed just with one inductor. 2) Input voltage 2.5 V - 5.5 V 3) Output current 1 A at 3.3 V 800 mA at 5.0 V 4) Incorporates soft-start function. 5) Incorporates timer latch system short protecting function. 6) High heat radiation surface mounted package VQFN020V4040 ●Application General portable equipment like portable audio or DSC/DVC ●Absolute Maximum Ratings Parameter Maximum applied power voltage Maximum input current Maximum input voltage Power dissipation Operating temperature range Storage temperature range Junction temperature *1 Symbol Vcc,PVCC Iinmax Lx1 Lx2 Pd Topr Tstg Tjmax Ratings 7.0 2.0 7.0 7.0 700 -25 to +85 -55 to +150 150 Unit V A V V mW ºC ºC ºC When installed on a 70.0 mm × 70.0 mm × 1.6 mm glass epoxy board.
