● Description ROHM’s High-efficiency Step-up Switching Regulator Built-in Power MOSFET BD8314NUV generates step-up output including 8 V or 10 V from 4 batteries, batteries such as Li1cell or Li2cell etc. or a 5 V fixed power supply line.
This IC allows easy production of small and a wide range of output current, and is equipped with an external coil/capacitor downsized by high frequency operation of 1.2 MHz, built-in 2.5 A rated 80 mΩ Nch FET SW, and flexible phase compensation system on board.

● Features
1) Incorporates Nch FET capable of withstanding 2.5 A/14 V.
2) Incorporates phase compensation device between input and output of ERROR AMP.
3) Small coils and capacitors to be used by high frequency operation of 1.2 MHz
4) Input voltage 3.0 V ~ 12 V
5) Output current 600 mA (3.5 V ~ 10 V) at 10 V 600 mA (3.0 V ~ 8 V) at 8 V
6) Incorporates soft-start function.
7) Incorporates timer latch system short protecting function.
8) As small as 3 mm× 3 mm, SON 10-pin package VSON010V3030

● Application
    General portable equipment like DSC/DVC powered by 4 dry batteries or Li2cell
